(i) In the periodic table, about 78% of elements are metals.
(ii) In a group, the metallic character decreases from top to battom and in a period the non-metallic character decreases from left to right.
(iii) The element Ho belongs to f-block.

D

`i,ii`

Text Solution

Verified by Experts

The correct Answer is:
C
In the periodic table, about 78% of elements are metals. The element Ho belongs to f-block.
The f-block elements are the lanthanides and actinides and are called inner transition elements.

The minimum amount of energy required to remove the most loosely bound electron from an isolated atom in the gaseous state in known as ionisation energy or ionisation enthalpy (IE_1) of the element. The energy required to remove the second electron from the monovalent cation is called second ionisation enthalpy (IE_2) . Similarly, we have third, fourth ..... inonisation enthalpies. The values of ionisation energy depends on a number of factors such as (i) size of the atom (ii) screening effect (iii) nuclear charge (iv) half filled and fully filled orbitals (v) shape of orbital. In a group, the ionisation energy decreases from top to bottom. In a period, the value of ionisation energy increases from left to right. In a period, the ionisation energy is lowest for the :
