|
|
Covalent bond |
A bond where two or more pairs of electrons are shared between two atoms. |
|
|
Molecule |
A neutral particle formed by neutral atoms. (H20 is a molecule because it is formed from H and O which are neutral atoms, NaCl is not a molecule because it is formed from a Na+ and Cl-). |
|
|

|
|
Subscript |
The number in a formula that represents how many atoms are present. (H20, 2 is the subscript and it tells you there are 2 hydrogen atoms present. |
|
|
Coefficient |
The number before a formula that tells you how many units or molecules of the formula are present. (3 H2O, 3 is the coefficient and it tells you that here are 3 water molecules present. |
