Study Notes
Atomic Structure/Nuclear Chemistry
- An atom is the smallest particle of an element that retains its properties.
- Dalton's atomic theory explains the Law of Conservation of Mass by stating matter cannot be created or destroyed during chemical reactions.
- Rutherford's gold foil experiment revealed the atom's structure, including a dense, positively charged nucleus.
- Electrons are located in the electron cloud surrounding the nucleus, while protons and neutrons are located in the nucleus.
- Protons have a positive charge, electrons have a negative charge, and neutrons have no charge.
- An atom is electrically neutral because it has an equal number of protons and electrons.
- Isotopes of an element differ in the number of neutrons.
- Atomic mass is the average mass of all isotopes of an element, weighted by their abundance.
- Mass number is the total number of protons and neutrons in an atom.
- Atomic number is the number of protons in an atom.
Chemical Nomenclature
- Ionic compounds are formed by the transfer of electrons between a metal and a nonmetal.
- Cations (positive ions) are written first, followed by anions (negative ions) in ionic compound formulas.
- Molecular compounds are formed by the sharing of electrons between two or more nonmetals.
- Molecular formulas show the number of each type of atom in a molecule.
- Chemical nomenclature follows specific rules for naming compounds.
Chemical Quantities
- 1 mole = 6.02 x 1023 particles (atoms, molecules, formula units).
- Molar mass is the mass in grams of 1 mole of a substance.
- Molar mass can be used to calculate the number of moles or atoms in a given mass.
- Percent composition shows the percentage by mass of an element in a compound.
