How do you find ionic charge?

Answer 1

In our Periodic Table, we got different elements each with different numbers of electrons or protons and neutron.

Electrons determines the reactivity and the charge of an element. it depends, on how many electrons does an element have and by arranging them in their order of the electrons shell, we will eventually get that in which shell there are extra or less electons.

by rule, the number of electrons that can exist in shells are the following.

1st shell: 2 electrons

2nd shell: 8 electons

3rd shell: 18 electrons

4th shell: 32 electrons

by puting the electrons of an element in this order, you will eventually get that in which electron shell you have extra or less electrons.

eg.

chlorine has 17 electrons, so it order is 2,8,7

Cl has 1 less electron to make the chlorine atom stable, so it charge is Cl-. it has a negative charge.

Sodium has 11 electrons, so it order is 2,8,1

Na has 1 extra electron that it wants to get rid of to make Na stable and its charge is Na+. it has positive charge.

Answer 2

well i think that the first group always has +1 the second gropus always has +2 but the 7th group i guess always has -1 ,but dnt confuse the transition elements too cause they differ.....
