Isotopes
Isotopes are atoms of the same element with the same number of protons but different number of neutrons. they have similar chemical properties as they have the same number of valence electrons but slightly different physical properties
Why are atoms reactive
They are reactive to obtain a stable noble gas electronic configuration with full electron shells.
Chemical bond
Chemical bond is an electrostatic attraction between oppositely-charged particles.
Melting and boiling points of Ionic compounds
Ionic compounds have a giant ionic crystal lattice structure. There are strong electrostatic forces of attraction between oppositely charged ion. therefore a lot of energy is needed to overcome the forces of attraction. Thus, ionic compounds have high melting and boiling point.
Electrical compounds of ionic compounds
Ionic compounds conduct electricity in molten and aqueous states but not in solids. In solid state, the oppositely charged ions are held in fixed positions by strong electrostatic forces of attraction, hence there are no free mobile ions to carry charges. In the aqueous and molten states, the electrostatic forces of attraction between oppositely charged ions have been overcome, hence there are free mobile ions to carry charges
Solubility
Mostly soluble in water
Insoluble in organic solvents.
