Question

give scientific reason ionic compound used in solid state and hard

Answer 1

HEY-----
--------DEAR---YOUR---ANSWER----




Ionic compounds are usually hard as the ions present in the ionic compounds are held together by the strong electrostatic forces of attraction.---:-) ---

Because ionic compounds are formed by alternating positive and negative ions, and because they are all held together with these strong electrostatic forces, the oppositely charged ions pack tightly with each other and form a crystal lattice structure that is extremely hard to break:-) :-) --



-- Sodium chloride, on the other hand, contains ions; it is an ionic compound. Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions. ... Molecular compounds contain discrete molecules, which are held together by sharing electrons (covalent bonding).:-) ----:-) :-) :-)
