4. 

The correct statement among the following regarding the element Unununium " is: 

1. It is an inner transition element.

2. It belongs to the 8th period in the periodic table.

3. It is a transition element.

4. It is a non-transition element.

The following property/ies decrease from left to right across the periodic table and increase from top to bottom:

(i) Atomic radius (ii) Electronegativity (iii) Ionisation energy (iv) Metallic character

Consider the following information about element P and Q :

                        Period number            Group number

P                               2                                 15

Q                               3                                 2

Then formula of the compound formed by P and Q element is :

(1) PQ         

(2) $P_3{Q}_2$           

(3)$Q_3{P}_2$            

(4)$P{Q}_2$
