Point out the wrong statement: In a given period of the periodic table,the $s$-block element has,in general,a lower value of

What are the properties associated with individual particles of matter?

Which blocks of the periodic table contain the representative elements?

In a period, the first ionisation enthalpy of the element at the extreme left and the negative electron gain enthalpy of the extreme right element, except noble gases, are respectively.

The element with a very high ionization enthalpy but zero electron gain enthalpy is ....

Identify the correct statements from the following.
$(i)$ In the periodic table,about $78 \%$ of elements are metals.
$(ii)$ In a group,the metallic character decreases from top to bottom and in a period the nonmetallic character decreases from left to right.
$(iii)$ The element $Ho$ belongs to $f-$block.
