Which of these is an ionic bond?
A
Nonmetal+Nonmetal
B
Metal+Nonmetal
C
Metalloid+Metalloid
D
Metal+Metal
Explanation: 

Detailed explanation-1: -Ionic bonds are generally between metals and non-metals. For e.g. Salt (NaCl) is an ionic bond that consists of Sodium (Na) which is a metal with positive charge combines with Chlorine (Cl), a nonmetal with a negative charge.

Detailed explanation-2: -Ionic bonds form only between metals and nonmetals. That’s because metals “want” to give up electrons, and nonmetals “want” to gain electrons. It takes energy to remove valence electrons from an atom and form a positive ion. Energy is released when an atom gains valence electrons and forms a negative ion.
