Inorganic Chemistry Chemistry – study of matter Matter – anything that occupy space and has mass. Composition Structure Changes that matter undergoes (Properties à Physical & Chemical) Energy associated in such changes Mass – refers to the amount of matter present in a material Weight – mass X pull of gravity Classifying matter: Origin Organic – living things Inorganic – nonliving things Composition Pure – has unique set of properties Elements – metal, metalloid, nonmetal Compounds – acid, base, salt, oxide à inorganic or organic Mixture Homogeneous – one phase (True solution) Heterogeneous – two or more phases Colloids Coarse dispersion (suspension) States (Phases) Solid, liquid, gas, plasma Matter Properties Physical – observable and measurable Intensive – depends on the identity of substance not the amount Ø Color, Solubility, Boiling point, Melting point, etc. Extensive – depends on the amount of matter present Ø Mass, Volume, Length, etc. Chemical – ability of a substance to change into another substance / ability to resist change Flammability, corrosion, oxidation resistance, etc. Changes (can be brought by physical agent (heat), + other substance) Physical – phase change Chemical – change in intensive properties ATOMIC STRUCTURE Democritus (Gk.) – a-tomos (indivisible particle) John Dalton – atomic theory J.J. Thomson – “plum pudding” model, atom contains (+) & (-) particles E. Rutherford – α particles scattering on gold foil N. Bohr – “planetary model” E. Schrodinger – “electron cloud” ATOMIC STRUCTURE John Dalton – atomic theory (1808) Main points 1. Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. 2. All atoms of any one element are identical. 3. The atoms of different elements vary in size and mass. 4. Compounds are produced through different whole-number combinations of atoms. 5. A chemical reaction results in the rearrangement of atoms in the reactant and product compounds. No change in the identity of atom. ATOMIC STRUCTURE J.J. Thomson – “plum pudding” model, atom contains (+) & (-) particles Rutherford – α particles scattering on gold foil ATOMIC STRUCTURE ATOMIC STRUCTURE (modern description of electron in an atom) Quantum numbers A. Principal (n) – approximate measure of the size of electron cloud. values: 1, 2, 3, 4,….. (positive integer) corresponding to the K, L, M, N,…. B. Azimuthal / Angular Momentum (l) – related to the shape of electron cloud, indicating if it is spherical, dumbbell shaped, or of more complex geometry. values: n-1 so 0, 1, 2, 3,….. corresponding to the s, p, d, f,…. C. Magnetic (ml) – related to the orientation of electron cloud in space. values: 0 for n=0, -1,0,+1 for n=1, -2,-1,0,+1+2 for n=2 D. Spin (ms) – gives the orientation of the magnetic component of an electron. Direction of the spin or rotation values: +1/2, -1/2 Principles: Aufbau (“building up”) Ølowest-energy orbitals filled up first Pauli’s Exclusion Principle ØNo two electrons can have the same set of quantum numbers ØOnly two electrons can occupy an orbital and must be in opposite spin. Hund’s rule ØDegenerate orbitals are filled up singly before pairing up. Heisenberg’s uncertainty principle ØIt is impossible to determine simultaneously the momentum and position of an electron. Fundamental particles of an ATOM Particle Symbol Charge Mass Discovery Proton p+ + 1.0073 u Ernest Rutherford Electron e̅ - 0.0005 u Joseph John Thomson Neutron no 0 1.0087 u James Chadwick The mass of the atom is taken from the sum of the masses of proton and neutron. The number of proton is represented by the atomic number of the element in the periodic table. The number of proton = number of electron in a neutral atom. The symbol 12C6 means The mass of C is 12 u Its atomic number is 6 (number of proton is 6 as well as electron) Existence of ISOTOPES – 12C6, 13C6, 14C6 The mass of an atom is taken from the average mass of its isotopes Ave. At.

Allotropes of C à diamond and graphite Allotropes of O à [O] is nascent, O2 is molecular and O3 is called ozone Compound – 2 or more atoms chemically combined Types Organic or Inorganic Molecular or Ionic (types of bond) Acid, base, salt or oxide Hydrated or anhydrous Electrolyte or non-electrolyte Formula writing Nomenclature Classical – ex. cupric sulfate CuSO4 Stock system – ex. copper (II) sulfate Laws on Chemical Combinations Law of Conservation of Matter (Lavoisier’s Law) Law of Definite proportions or (Law of Definite Composition / Law of Constant Composition / Proust’s Law) a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation. Law of Multiple Proportions (Dalton’s Law) When two elements combine with each other to form more than one compound, the weights of one element that combine with a fixed weight of the other are in a ratio of small whole number. Laws on Chemical Combinations Law of Combining Volume (Gay Lussac’s Law) when gases are produced or combine in a chemical reaction, they do so in simple ratio by volume given that all the gases are at same temperature and pressure. This law can be considered as another form of law of definite proportions. The only difference between these two laws of chemical combination is that Gay Lussac’s Law is stated with respect to volume while law of definite proportions is stated with respect to mass. brass ( volume Avogadro’s Law under same conditions of temperature and pressure, equal volume of all the gases contain equal number of molecules. This implies that 2 litres of hydrogen will have the same number of molecules as 2 litres of oxygen given that both the gases are at same temperature and pressure. equal volume / gases) = equal * of molecules Forces of attraction INTRAMOLECULAR FORCES (forces that hold the atoms together within a single molecule) 1- Ionic bond – transfer of e- lit ) 5 Covalent bond – sharing of e- ( as) Polar – unequal sharing IP.tn Nonpolar – equal sharing IN E). } intra INTERMOLECULAR FORCES (forces that exist between separate molecules) Van der Waals Keesom (dipole-dipole) ex.

SOLUBILITY RULES § Almost all group I-A and ammonium salts are soluble in water. § All nitrates, acetates, chlorates and perchlorates are soluble in water. § All common chlorides are soluble, except AgCl, PbCl2 and Hg2Cl2. § Common bromides and iodides show approximately the same solubility property as chlorides, but there are some exceptions. – As the halide ions increase in size, the solubility of their slightly soluble compounds decrease. § Fluorides are water soluble except, MgF2, CaF2, SrF2, BaF2 and PbF2. § All sulfates are soluble except BaSO4 and PbSO4; CaSO4, SrSO4, HgSO4, and Ag2SO4 are moderately soluble. § All sulfides are insoluble, except those of alkaline earth metals, alkali metals and ammonium ion. § All oxides and hydroxide are insoluble except alkali metal compounds. – Oxides and hydroxides of Ca, Sr and Ba are slightly soluble § All phosphates, carbonates and arsenates are water insoluble except those of alkali metals and ammonium ion. – MgCO3 is moderately soluble Bunsen Flame Bunsen Flame The lower oxidizing zone (c) is situated on the outer border of b and may be used for the oxidation of substances dissolved in beads of borax, sodium carbonate, or microcosmic salt. The upper oxidizing zone (d) consists of the non- luminous tip of the flame; here a large excess of oxygen is present and the flame is not so hot as at c. The upper reducing zone (e) is at the tip of the inner blue cone and is rich in incandescent carbon; it is especially useful for reducing oxide incrustations to the metal. The lower reducing zone (f) is situated in the inner edge of the mantle next to the blue cone and it is here that the reducing gases mix with the oxygen of the air; it is a less powerful reducing zone than e, and may be employed for the reduction of fused borax and similar beads.

(rad) radiation absorbed dose is a more universal unit, it is a measure of the energy deposited in unit mass of any material by any type of radiation. The dose equivalent unit (rem) roentgen equivalent man rem has been developed to account for the differences in effectiveness of different radiations in causing biological damage. In radiobiology, the rem is defined as Rem = rad ´ RBE RBE is the relative biological effectiveness of the radiation. The basic unit for quantifying radioactivity (i.e. describes the rate at which the nuclei decay). Curie (Ci): A unit of radioactivity. A curie is defined as 3.7 x 1010 disintegrations per second. In 1980, The new basic unit for quantifying radioactivity. Becquerel (Bq): SI unit of radioactivity. One becquerel is equal to 1 disintegration per second. Sievert (Sv): The unit of absorbed dose equivalent and equal to 100 rem. GLASS Boron reduces the coefficient of expansion. Potassium gives a brown and light resistant glass.
