how does the periodic table help in predicting the formula of a stable ionic compound?\nmetals in group 1 form cations with a -1 charge.\nmetals in group 2 form cations with a +2 charge.\nmetals in group 1 form anions with a +1 charge.\nmetals in group 2 form anions with a -2 charge.

how does the periodic table help in predicting the formula of a stable ionic compound?\nmetals in group 1 form cations with a -1 charge.\nmetals in group 2 form cations with a +2 charge.\nmetals in group 1 form anions with a +1 charge.\nmetals in group 2 form anions with a -2 charge.

Answer

Brief Explanations:

Metals in Group 1 have 1 valence - electron and lose it to form a +1 charged cation. Metals in Group 2 have 2 valence - electrons and lose them to form a +2 charged cation. Anions are negatively charged and cations are positively charged.

Answer:

B. Metals in Group 2 form cations with a +2 charge.
