How do you find the common ion charge?
To find the ionic charge of an element you’ll need to consult your Periodic Table. On the Periodic Table metals (found on the left of the table) will be positive. Non-metals (found on the right) will be negative.

What are the common ion charges of groups 1a 8a?
Group I (alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge.
What is the charge of an ion?
Since the electric charge on a proton is equal in magnitude to the charge on an electron, the net electric charge on an ion is equal to the number of protons in the ion minus the number of electrons.
What is the charge of the common ion formed by BA?
2+
The charge on the barium ion is 2+, meaning it has a positive charge of two. The barium ion gets its charge by losing two electrons to become a positively charged ion called a cation. Atoms become ions in order to mimic the electron configuration of the nearest noble gas.
What is the charge of the common ion formed by MG?
A magnesium atom must lose two electrons to have the same number electrons as an atom of the previous noble gas, neon. Thus, a magnesium atom will form a cation with two fewer electrons than protons and a charge of 2+.
What is the charge of an element?
We know that atoms are made up of electrons and protons and are held together by a force called electromagnetic force. In standard forms, the elements have no net charge. It means the number of negatively charged electrons is equal to the number of positively charged protons.
What is the charge of Group 11?
Although the most important oxidation state for group 11 is +1, the elements are relatively unreactive, with reactivity decreasing from Cu to Au.
What is the charge of Group 14?
The elements in group 13 and group 15 form a cation with a -3 charge each. And elements in group 14 have a charge of -4.
