Answer:
A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. They both achieve a more stable electronic configuration through this exchange.
Answer:
★ Molecular geometry is described by VSEPR theory, which basically states that electron pairs around a central atom will repel each other, and get as far apart as possible, in three dimensions.

Hope you have a great day :)
Answer:
5.12
Explanation:
5.22 x 10 - 3 = [?] x 10 - 2 (move - 2 to the other side with changed sign)
5.22 x 10 - 3 + 2 = [?] x 10 (divide both sides by 10)
[?] = (5.22 x 10 - 1) / 10
[?] = 5.12
