What is a reactant?
The force of attraction that keeps positive and negative ions together in a compound.
What is an ionic compound?
This occurs when attractive forces form between molecules instead of between atoms.

This is the concave curve in the upper surface of water in a measuring cup.
What is Meniscus?
When there is the same number of atoms of each element on both sides of the equation this has occurred.
What is a balanced equation?
An attraction between the shared electron and protons in each nucleus that hold atoms together.
