Question

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

Explanation:

An ionic bond forms between a metal and a non - metal. Calcium ion ($Ca^{2 + }$) is a metal ion. Fluorine forms a $F^-$ ion with a - 1 charge. Oxygen forms an $O^{2 - }$ ion, carbon usually forms covalent bonds, and neon is a noble gas and is chemically inert. For a 1:1 ratio ionic bond with $Ca^{2+}$, a non - metal that forms a - 2 charge ion is needed. Oxygen forms $O^{2 - }$ and will bond with $Ca^{2+}$ in a 1:1 ratio.

Answer:

B. one atom of oxygen
