and high electron affinities. Due to low ionization energies of the metals they have tendency to lose an electron but the high electronegativitiy and high electron affinities non metals have ability to accept an electron. so in this way these both form ionic bond with each other.
- Soluble in water, conduct electricity in molten state, have high M.P and B.P, Crystalline solids.
- Some elements has an outermost shell & 18 electrons which all are ionized and follow the configuration of (ns2 np6 nd10). This type of configuration is given by the cations of IB and IIB group. This type of configurations is called Pseudo inert gasinert gas configuration.
- In inert gas configuration, ns2 np6 configuration is followed. in this type of configuration the nuclear charge is not strong sufficiently to keep the electron remain in their position. so these elements give d orbital electron easily. example: Fe2+, Co2.
