Ionization Energies

Give reasons ...

Question

Give reasons for the following:
Ionisation potential of element increases across a period.

Open in App

Solution

As we go from left to right in a period electrons are added to the same valence shell.Due to this atomic size decreases and nuclear charge increases. As nuclear charge increases, the energy required to remove an electrln increases and hence ionization potential increases across a period

Q. Assertion :Ionisation potential increases with increase in nuclear charge of the elements. Reason: Ionization energies increase moving from left to right across a period.

Q. Give a reason for the following.
Ionisation potential increases across a period, from left to right.

Q. Assertion :Ionisation potential of the element increases across a period. Reason: Left side columns of the periodic table have metals while right columns have non-metals so in general as we move from left to right ionisation potential increases.

Q. Assertion :A decrease in ionisation potential of an element leads to decrease in non-metallic character of the element. Reason: As ionisation potential decreases, its ability to loose electron increases while its ability to gain electron decreases

Arrange the elements N, P O and S in the order of
(i) increasing first ionisation enthalpy.

(ii) Increasing non-metalic character. Give reason for the arrangement assigned.
