If an element forms a 1- ion, in which group of the periodic table would you expect to find it?
O A. 18
B. 2
C. 1
O D. 17

D. 17

Explanation:

Halogens (group 17) are most likely to form a -1 ion. This is because they want to complete their octet. A prime example of this is sodium chloride. Sodium chloride is an ionic compound. Sodium gives up its valence electron, therefore, recieving a +1  charge, and Chlorine takes it, giving it a -1 charge. Chlorine is also in group 17, halogens.

the answer is D.17

Explanation:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
