How does the periodic table help in predicting the formula of a stable ionic compound?
A.Metals in Group 1 form cations with a –1 charge.
B.Metals in Group 2 form cations with a +2 charge.
C.Metals in Group 1 form anions with a +1 charge.
D.Metals in Group 2 form anions with a –2 charge.

Respuesta :

A. This is a FALSE statement because Metals in Group 1 form cations with a +1 charge and not -1. 

B. This is a TRUE statement. 

C. This is a FALSE statement because metals do not form anions i.e. negatively charged ions but form cations i.e. positively charged ions. 

D. This is a FALSE statement because metals do not form anions i.e. negatively charged ions but form cations i.e. positively charged ions.
