Q.

Given below are two statements:

Statement (I): Both metals and non-metals exist in p and d-block elements.

Statement (II): Non-metals have higher ionisation enthalpy and higher electronegativity than the metals.

In the light of the above statements, choose the most appropriate answer from the options given below:              [2024]

1 Both Statement I and Statement II are false  
2 Both Statement I and Statement II are true  
3 Statement I is false but Statement II is true  
4 Statement I is true but Statement II is false  

Ans.

(3)

Statement (I): s, d, and f block has only metals while p block has metals, non-metals and metalloids. Thus statement (I) is false.

Statement (II): Non-metals are electronegative i.e. have a tendency to attract electrons. Statement (II) is true.
