Ionic Bonds
Bond between metal and non-metal, with electron transferred from metal to non-metal
Acids & Base
Acid : Anything that dissociates to produce Hydrogen (H+) ions. Example Hydrochloric acid: HCL --> H + CL
Usually acids can be divided into three major types. First one is binary acid, second one is oxyacid, and the last one is carboxylic acid. Binary acids are all written in “H-A” form, which means hydrogen bond to a nonmetal atom.
Base : Anything in solution that dissociates to produce Hydroxide (OH-) ions. Example: Sodium Hydroxide NaOH - Na + OH-

Naming compounds
Ionic compounds
-
-
Name metals that can have different oxidation states using roman numerals to indicate positive charge
Covalent compounds
-
-
Use the prefixes mono-, di-, tri-.... to indicate the number of that element in the molecule
Polyatomic compounds
Rule 1. The cation is written first in the name; the anion (takes electrons) is written second in the name.
Rule 2. When the formula unit contains two or more of the same polyatomic ion, that ion is written in parentheses with the subscript written outside the parentheses.
pH scale
-
-
1 to 14 scale, 7 is neutral
Periodic Table
-
Period
Rows in periodic table. Elements in the same period share the same number of shells, valence electron number increase from left to right
Balancing Equations
An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
