Given the number of valence electrons in neutral atoms, predict the charge of the ions each will form.

one valence electron

two valence electrons

six valence electrons

seven valence electrons

eight valence electrons

a. generally does not form ions

b. forms ion with 2- charge

c. forms ion with 2+ charge

d. forms ion with 1+ charge

e. forms ion with 1- charge

The charges of the ions of the given valency electrons are as follows;

one valence electron → +1

two valence electrons → +2

six valence electrons → -2

seven valence electrons → -1

eight valence electrons → does not form ion.

The valency electron of a neutral atom determines the charge it possess

when it forms an ion. They may form cations or anions or even possess no  

charge.

A neutral atom with  one valency electron will form +1 charge.

A neutral atom with  two valency electron will form +2 charge.

A neutral atom with  six valency electron will form -2 charge.

A neutral atom with  seven valency electron will form -1 charge.

A neutral atom with  eight valency electron will not form any ions.
