Periodic Table with Charges

A periodic table with charges shows the most common ionic charges for each element. It is useful for predicting ions and writing ionic compound formulas.

Group 1 elements usually form +1 ions, Group 2 elements usually form +2 ions, halogens usually form -1 ions, and transition metals often have multiple charges.

Element charge result

Sodium usually forms Na+

Symbol: Na
Common ionic charges: +1
Common ions: Na+

Sodium is an alkali metal, so it commonly loses one electron and forms a +1 ion.

How to use this charge table

Main group elements

Use the group number to predict common charges for alkali metals, alkaline earth metals, halogens, oxygen, and nitrogen.

Transition metals

Check the compound name or roman numeral because iron, copper, tin, lead, mercury, and other metals can have more than one charge.

Ionic formulas

Balance total positive and negative charges so the final ionic compound has a net charge of zero.
