Expression of the Composition or Structure of a Chemical

Compound

• Formulas for molecules use chemical symbols with subscript numbers to show the number of atoms of each element

• Ex: O2 for molecular oxygen

What is a Molecule?

• A unit of matter that is the smallest particle of an element.

• Chemical combination of atoms (as a compound) capable of retaining chemical identity with the substance in mass.

Explanation

• Covalent bonds holds atoms of the same or different non-metal elements together by sharing pairs of electrons. Atoms joined by covalent bonds form molecules. Depending on the number of shared pairs of electrons between two atoms, the covalent bond can be described as a single or a multiple covalent bond.

• A single covalent bond is when 2 electrons are shared between atoms. A double bond is when 4 electrons are shared and Triple is when 6 electrons are shared.

Rules to Name Molecular Compounds

1. The first element in the formula is named first, using the full element name.

2.The second element is named using the suffix -ide.

3. Prefixes are used to see the numbers of atoms present.
