Question

metals in group 1 of the periodic table can form ionic bonds with elements from which of these groups? choose 1 answer: a group 2 b group 17 c group 18

Explanation:

Metals in group 1 have 1 valence electron and readily lose it to form a +1 ion. Elements in group 17 have 7 valence electrons and gain 1 electron to form a -1 ion. Oppositely - charged ions form ionic bonds. Group 2 elements are metals that form +2 ions, and group 18 elements are noble - gases which are generally unreactive.

Answer:

B. group 17
