Answer

See explanation below.

Work Step by Step

a) Ionization energy is amount of energy required to remove an electron from the isolated gaseous atom to convert it into positively charged ion. Along the period ionization energy increases and metallic character decreases. 2 b) Atomic radius is distance between nucleus and outermost shell. Along period atomic radius and metallic character decreases. 3 c) Along a period as number of electron increases metallic character decreases. 4 d) Effective nuclear charge is actual number of charge experienced by an electron. during a period of time as effective nuclear charge increases metallic character decreases.
