Answer:
c. electrical neutrality.
Explanation:
A <em>crystalline solid</em><em> possesses a rigid and long-range order; its atoms, molecules, or ions occupy specific positions.</em> The arrangement of such particles in a crystalline solid is such that the net attractive intermolecular forces are at their maximum.
Ionic crystals, particularly, have two important characteristics:
(1) They are composed of charged species.
(2) Anions and cations are generally quite different in size.
The forces holding the atoms together are electrostatic attractions. Examples of these types of crystals include NaCl, LiF, MgO, CaCO₃.
<u>Since they are composed of anions and cations, in stoichiometric amount, they are to be said electrically neutral.</u>
4 is correct for this one
Answer:
Opposite poles of attract each other and make bonds.
Explanation:
Those compounds are soluble in water which have polar nature means that make poles with other atoms while on the other hand, those compounds which doesn't have polar nature are dissolve in non-polar solvent. The polar nature of compounds is due to their difference in electronegativities so in polar compounds opposite poles attract one another and make bonding with each other.
