Which pair of elements can form ionic bonds

A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.

metal and non metsl

Explanation:

Generally ionic bonds are formed when Electronegativity difference between two bonded atoms is >1.7

And observed between metal and non metal

Example, NaCl, MgCl2 and Fecl3 etc

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
