Compounds, Chemical, Formula, and Covelent Bonds

Is a chemical bond formed when two atoms share one or more pairs of the valence electron

Is a group o atoms held together by covalent bonding that acts like an independent unit.

A molecule hat has a partial positive end and partial negative and because of unequal sharing of electrons.

is a group of chemical symbols and numbers represent the elements and the number of atoms of each element that make up a compound

Shows the valence electrons

Shows atoms and lines; each line represent one shared pair of electron

Balls represent atoms and sticks represents bonds; used to show bond angles.

Spheres represent atoms used to show three-dimensional arrangement of atoms.
