Assertion (A): In ionisation potential Vs atomic number curve peaks are occupied by inert gases
Assertion (R): `ns^(2)np^(6)` configuration is stable

Why are elements having ns^(2)np^(6) configuration called noble gases?

The peaks in ionisation potential curves are occupied by

Assertion (A): Ionisation potential of K is numerically the same as electron affinity of K^(+) Assertion (R): Ionisation potential and electron affinity both depend on screening effect

Assertion (A): Ionisation potential across a period is Li lt B lt Be lt C Assertion (R): Ionisation potential decreases with decrease in atomic size

Assertion (A): Ionisation potential of 'N' is greater than 'O' Assertion (R): Nitrogen has 5 unpaired electrons

Assertion (A) : Ionisation potential of Be (atomic number 4 ) is than B (atomic number 5) Reason (R ) : The first electron released fromm Be is of p orbitals but that from B is of a orbitals.

Assertion (A) : Ionisation potential of Be (atomic number 4 ) is more than B (atomic number 5) Reason (R ) : The first electron released fromm Be is of p orbitals but that from B is of s orbitals.

Assertion (A) : The ionisation energy of N is more than that of O Reason (R ) : Electronic configuration of N is more stable due to half - fillied 2p orbitals

Assertion (A) : The ionisation energy of N is more than that of O Reason (R ) : Electronic configuration of N is more stable due to half - fillied 2p orbitals

Assertion (A) : The electronic configuration of nitrogen atom is represented as Reason (R ) : The electronic configuration of the ground state of an atom is the one which has the greatest multiplicity
