Essential Understandings

Chemical formulas are used to represent compounds. Subscripts represent the relative number of each
type of atom in a molecule or formula unit. The International Union of Pure and Applied Chemistry
(IUPAC) system is used for naming compounds.

When pairs of elements form two or more compounds, the masses of one element that combine with a
fixed mass of the other element form simple, whole-number ratios (Law of Multiple Proportions).

Compounds have different properties than the elements from which they are composed.
Essential Knowledge, and Skills
In order to meet this standard, it is expected that students will

name binary covalent/molecular compounds.

name binary ionic compounds (using the Roman numeral system where appropriate).

write chemical formulas for certain common substances, such as ammonia, water, carbon monoxide,
carbon dioxide, sulfur dioxide, and carbon tetrafluoride.

use polyatomic ions for naming and writing formulas of ionic compounds, including carbonate, sulfate,
nitrate, hydroxide, phosphate, and ammonium.
SOL Standards
CH.3 The student will investigate and understand how conservation of energy and matter is expressed in
chemical formulas and balanced equations.
