Which nonmetal would an ion of ca2+ most likely ionically bond with in a 1: 1 ratio? a) one atom of neon b) one atom of carbon c) one atom of oxygen d) one atom of fluorine

Ca2+ would bond to any element in a 1 to 1 ratio that had an equal and opposite charge.

Neon is a noble gas, and doesn’t form bonds m

Carbon isn’t typically found in ion state, but if it did, it would likely by C4+

Flouring in ionic state is F1-, so you would need 2 flourines to cancel the 2+ charge of Calcium

Then the only option left would be Oxygen which, when in ion form is found be 2-
