Question

in which of the following compounds are atoms held together by ionic bonds involving the electrostatic attraction of opposite charges? (pick all that apply)
□ ncl₃
□ ag₂o
□ nacl
□ h₂o
□ c₆h₁₂o₆
□ pcl₃
□ mg₃n₂
□ fes

Explanation:

Ionic bonds form between a metal and a non - metal through the transfer of electrons creating ions with opposite charges that attract. $NCl_3$ is a covalent compound as both N and Cl are non - metals. $Ag_2O$ has ionic bonds as Ag is a metal and O is a non - metal. NaCl is an ionic compound with Na (metal) and Cl (non - metal). $H_2O$ is a covalent compound with two non - metals H and O. $C_6H_{12}O_6$ is a covalent compound with non - metals C, H, and O. $PCl_3$ is a covalent compound with non - metals P and Cl. $Mg_3N_2$ has ionic bonds with Mg (metal) and N (non - metal). FeS has ionic bonds with Fe (metal) and S (non - metal).

Answer:

B. $Ag_2O$, C. NaCl, G. $Mg_3N_2$, H. FeS
