FEU Biochemistry Property. All forms of replicatin are prohibited. Seek approval from Ms. Jessa Natividad and Ms. Erika Viloria 8/13/24 Chemical Writing Lab Module 1 Far Eastern University IAS – Dept. of Mathematics Biochemistry Cluster 1 Outline Chemical Formulas & Nomenclature Ionic Compounds Binary Covalent Compounds Chemical Equation Writing 2 1 FEU Biochemistry Property. All forms of replicatin are prohibited. Seek approval from Ms. Jessa Natividad and Ms. Erika Viloria 8/13/24 Chemical Formulas & Nomenclature 3 Ionic Compounds Ionic compounds are compounds made up of ions that are formed when atoms donate and receive electrons. The transfer of electrons lead to positive and negative charges (ions) that attract each and form an ionic bond. Cations – positively-charged atoms or molecules Anions – negatively-charged atoms or molecules Naming ionic compounds is usually based on the cation’s name followed by the anion’s name. 4 2 FEU Biochemistry Property. All forms of replicatin are prohibited. Seek approval from Ms. Jessa Natividad and Ms. Erika Viloria 8/13/24 Ionic Compounds Types of Ionic compounds 1. Binary ionic compounds – ionic compounds formed from just two elements and commonly ends with the suffix –ide 2. Ternary compounds – ionic compounds formed from a combination of more than two elements. They have variety of suffixes other than -ide 5 Rules in Naming Cations Cations formed from metal atoms bears the name of the metal itself. Ion Name !! Potassium ion "#! Sodium ion $#"! Calcium ion %&"! Magnesium ion 6 3 FEU Biochemistry Property. All forms of replicatin are prohibited. Seek approval from Ms. Jessa Natividad and Ms. Erika Viloria 8/13/24 Rules in Naming Cations Some metal ions can have more than one charge such as those in the transition metals. We name them as the name of the metal itself and a Roman numeral enclosed in parenthesis to indicate the charge. Ion Name '( "! Iron (II) ion '( #! Iron (III) ion $)! Copper (I) ion $)"! Copper (II) ion 7 Rules in Naming Cations Usually, metals with two charges only can be named using their root Latin name / old metal name followed by the suffix –ous and –ic. The suffix –ous indicates the ion with the lowest charge, while –ic indicates highest. Ion Name Old Name Suffix '( "! Ferrous ion Latin: Ferrum -ous for +2 charge '( #! Ferric ion Latin: Ferrum -ic for +3 charge $)! Cuprous ion Latin: Cuprum -ous for +1 charge $)"! Cupric ion Latin: Cuprum -ic for +2 charge 8 4 FEU Biochemistry Property.

All forms of reproduction or replication are prohibited. Seek permission from Ms. Jessa Natividad and Ms. Erika Viloria 8/14/24 Forces of Attraction INORGANIC CHEMISTRY 3 Forces of Attraction Attractive forces between molecules allows them to form condensed phases of matter. There are two primary types of attractive forces: 1. Intramolecular forces are the forces that hold atoms together within a molecule (also known as chemical bonds. 2. Intermolecular forces are forces that exist between molecules. 4 2 FEU BIOCHEMISTRY PROPERTY. All forms of reproduction or replication are prohibited. Seek permission from Ms. Jessa Natividad and Ms. Erika Viloria 8/14/24 Intramolecular Forces of Attraction Intramolecular forces are the forces that hold atoms together within a molecule. There are three types of chemical bonds: 1. Ionic Bond 2. Covalent Bond 3. Metallic Bond 5 Intramolecular Forces of Attraction Ionic bond It is formed when there is a complete transfer of valence electron between two atoms producing cations and anions. The two charged particles are then attracted to each other by Coulombic forces. 6 3 FEU BIOCHEMISTRY PROPERTY. All forms of reproduction or replication are prohibited. Seek permission from Ms. Jessa Natividad and Ms. Erika Viloria 8/14/24 Intramolecular Forces of Attraction Covalent bond This bond is formed between atoms that have similar electronegativities. Because both atoms have similar affinity for electrons and neither tends to donate them, they share electrons in order to achieve octet configuration and become more stable. There are two types of covalent bonds due to the electronegativity difference of participating atoms: 1. Nonpolar covalent bond 2. Polar covalent bond 7 Intramolecular Forces of Attraction Nonpolar covalent bond A nonpolar covalent bond is formed between same atoms or atoms with very similar electronegativities—the difference in electronegativity between bonded atoms is less than 0.4. 8 4 FEU BIOCHEMISTRY PROPERTY. All forms of reproduction or replication are prohibited. Seek permission from Ms. Jessa Natividad and Ms. Erika Viloria 8/14/24 Intramolecular Forces of Attraction Polar covalent bond A polar covalent bond is formed when atoms of slightly different electronegativities share electrons. The difference in electronegativity between bonded atoms is between 0.4 and 1.8. Electron-poor Region H F Electron-rich Region 9 Intramolecular Forces of Attraction Metallic bond This type of covalent bonding specifically occurs between atoms of metals, in which the valence electrons are free to move through the lattice. This bond is formed via the attraction of the mobile electrons (sea of electrons) and the fixed positively charged metal ions. 10 5 FEU BIOCHEMISTRY PROPERTY.

There are three types of intermolecular forces of attraction: 1. Dipole – dipole interactions 2. Hydrogen bonding 3. Van der Waals forces / London dispersion forces 12 6 FEU BIOCHEMISTRY PROPERTY. All forms of reproduction or replication are prohibited. Seek permission from Ms. Jessa Natividad and Ms. Erika Viloria 8/14/24 Intermolecular Forces of Attraction Dipole-dipole interactions These forces occur when the partially positively charged part of a molecule interacts with the partially negatively charged part of the neighboring molecule. 13 Intermolecular Forces of Attraction Hydrogen bonding This is a special kind of dipole-dipole interaction that occurs specifically between a hydrogen atom bonded to either an oxygen, nitrogen, or fluorine atom. 14 7 FEU BIOCHEMISTRY PROPERTY.
