Periodic Table Information

The periodic table can provide information about the number of protons, neutrons, electron shells, valence electrons, and ionic charge of an element.

Cation Formation

A cation is a positively charged ion formed when an atom loses one or more electrons.

Ionic Compound

An ionic compound is formed by the electrostatic attraction between positively charged cations and negatively charged anions.

Chemical Equation Balancing

Balancing a chemical equation ensures that the number of atoms of each element is the same on both sides of the equation.
