CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313350 Assertion :
Generally, ionisation enthalpy increases from left to right in a period.
Reason :
When successive electrons are added to the orbitals in the same principal quantum level, the shielding effect of inner core of electrons does not increase very much to compensate for the increased attraction of the electron to the nucleus.

1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If Assertion is false but Reason is true.
CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313351 Which of the following does not affect the ionisation potential of the atom?

1 Nuclear charge
2 Stable configuration
3 Penetration effect
4 None of these
CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313352 Assertion :
Ionisation potential of K is numerically the same as electron affinity of \({{\rm{K}}^{\rm{ + }}}\)
Reason :
Ionisation potential and electron affinity both depends on screening effect

1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If Assertion is false but Reason is true.
