Solutions

Expert Solution

atomic radii: The distance between center of nucleus and outer most shell is called atomic radus of the atom.

Haf of the distance between the two bonded aoms is called atomic radii

ionic radii: Haf of the distance between theions is called ionic radii

ionization energy : The amount of energy is required to remove an electron form its nutral atom is called ionisation energy.It is endothermic reaction delta H is positive

M(g) ----------> M^+(g) + e^- IP = +ve

electron affinity:The amount of energy is released whan an electrons is added to isolated gas atom is called electron affinity. it is exothermic reaction deltaH is negetive.

X(g) + e^- -----------> X^- (g) Ea = -ve
