Front

What is a valence electron?

Back

A valence electron is an electron that is associated with an atom and can participate in the formation of a chemical bond.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations is important because it ensures that the law of conservation of mass is obeyed, meaning the number of atoms of each element is the same on both sides of the equation.

Front

What does it mean for a compound to be neutral?

Back

A neutral compound has no overall charge, meaning the total positive charge from cations equals the total negative charge from anions.
