All About Ions


All about ions

How ions form- an ion is formed when an atom of any element either loses or gains one or more electrons.

Why ions form - ions for because neutral atoms either gain or lose electrons to have a full valence electron energy level.

What kinds of ions form - There can be positively charged ion which is a cation and negatively charged ions which are anions

How to determine ion charges - A cation ion has fewer electrons than protons; this gives it a positive charge. An anion is an ion with more electrons than protons, hence a net negative charge.
