Define Ionisation potential. How it changes form left,to right in 2nd period?

Define ionisation potential. State its change down a group.

How does the ionisation enthalpy vary from left to right in the transition series ?

Why the 1st Ionisation potential of N_2 is higher than O_2 ?

2nd Ionisation potential of oxygen is greater than 2nd ionisation potential of Nitrogen— Explain.

What changes in the following properties are observed while moving from left to right along a period & from top to bottom in a group? (1) Atomic volume, (2) Valency, (3) Electronegativity.

2nd ionisation potential of Be is greater than the 1st ionisation potential of B but less than 2nd ionisation potential of B - explain .

Choose the number of correct statement(s) form the following: ist ionization potential of B is higher than that of Be electron affinity of O is higher than that of S [Ar] 4s^23d^3 is the electronic configuration of Mn^(+2) Iind ionisation potential of Na>ist ionisation potential of Na 1st ionisation potential of N>IInd ionisation potential of N electronegativity of Cl>electronegativity of F C rarr C^+2 change is called IInd ionisation potential of carbon energy is required to convert He rarr He^- conversion of o rarr o^2 exothermic

Elements A, B ,C and atomic number (Z-2), Z and (Z+1) respectively. Of these, B is an inert gas. (a) which one of these has the highest electronegativity? (b) which one of these has the highest value of ionisation potential (c) what is the compound formed by the combination of A and C?

Eelctroncgativity of fluorine is greater than chlorine, but electron affinity is higher in chlorine that fluorine— explain.Why 2nd ionisation potential is always greater than 1st ionisation potential?
