is febr3 ionic or covalent
Ionic bonds are formed when there is a strong difference between the electronegativity of the two atoms involved. Also, a metal is almost ALWAYS involved in ionic bonding. In fact, I can't think of any ionic compounds not involving metals.A good example of ionic bonding is common table salt, sodium chloride.onic bonds are formed when there is a strong difference between the electronegativity of the two atoms involved.
