7) An ionic bond could form between: (a) magnesium and potassium
(b) fluoride and chloride
(c) nitrogen and rubidium
(d) chlorine and xenon

Explanation:

the answer is nitrogen and rubidium (C)

Explanation:

ionic bonds only form between metals and non-metals

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.
