Give reasons for
Atomic size of an element depends on the nuclear charge of that element.

Atomic mass of an element is

Atomic mas of an element is :

Give reason Ionisation potential increases with increase in nuclear charge of the elements.

All atoms of an element are identical.

Explain why Ionisation potential increases with increase in nuclear charge of the elements.

Energy is released when an electron is added to neutral isolated gaseous atom in its ground state to give monoanion and this is known as EA , or Delta_(eg)H_(1)^(ɵ) . The greater the amount of energy released the greater is the EA . EA is expressed in eV a"atom"^(-1) or kcal or K\kJ mol^(-1) . The EA values of element depends on the following: i. Nuclear charge ii. Electroniv configuration iii. Atomic size iv. chemical environment

Give reasons for Properties of elements are periodic functions of their atomic numbers and not atomic weights.

Are strong nuclear forces charge dependent?

Give reason Atomic size of group 18 [0 group] elements is more than the atomic size of group 17 [VIIA] elements
