Question

what do metals from positive ions and non metals from negative ions????plz tell​

Answer 1

Answer:

Forming positive ions :

Metal atoms lose electrons from their outer shell when they form ions:

the ions formed are positive, because they have more protons than electrons

the ions formed have full outer shells

for elements in groups 1, 2 and 3, the number of electrons lost is the same as the group number .

Forming negative ions :

The outer shells of non-metal atoms gain electrons when they form ions:

the ions formed are negative, because they have more electrons than protons

the ions formed have full outer shells

for groups 6 and 7, the number of electrons gained is equal to: 8 - group numbe.
