Answer any of the following four questions using the following section of the periodic table: 

A. Which metal is the most reactive? 

(i) (i) P  

(ii) Q 

(iii) Y 

(iv) Z 

B. The fluorine Q, R, and T family is referred to as 

(i) Halogens  

(ii) Alkali metal  

(iii) Transition metal  

(iv) Noble gases 

C. Which of these corresponds to the correct element for groups 2 and 15 respectively?

(i) Group2- Magnesium, Group15- Nitrogen

(ii) Group2- Nitrogen, Group15- Magnesium

(iii) Group2- Carbon, Group15- Nitrogen

(iv) Group2- Magnesium, Group15- Bromine

D. Name of the element P placed below carbon is 

(i) Silicon  

(ii) Hydrogen  

(iii) Nitrogen  

(iv) Magnesium 

E. Compare X and P with respect to the size of atoms.  

(i) X is bigger in size than P  

(ii) X is smaller in size than P  

(iii) X is the same as P  

(iv) None of these  

A. P belongs to the the14th  group, which is the carbon family and the element present in that group are non-metal. Q belongs to the 17th group, which are halogens, and they are also non-metal. Y and Z belong to group 1, and the metals of this group are known as alkali metals. Z is the most reactive metal as the metallic character increases as we move down the group. Hence, the correct option is (iv) Z. 

B. The family of fluorine is known as Halogens.  

Hence, the correct option is (i) Halogens.

C. Magnesium is the second element of group 2. Elements of the Group 2 are known as alkaline earth metals, and the first element is beryllium. Nitrogen belongs to group 15, and elements of this group come under nitrogen, and the group is known as the nitrogen family.

Hence, the correct option is (i) Group2- Magnesium, Group15- Nitrogen.  

D. Carbon belongs to the group14. The second element of this group is silicon. The group is called as carbon family.  

Hence, the correct option is (i) Silicon. 

E. The element X is Na, and the P element is Si. The atomic number of Na is 11, and the atomic number of silicon is 14. As the number of electrons increases, the number of protons also increases and hence the nuclear charge increase. Because of the increase in the nuclear charge, the attraction between the nucleus and the valence electron also increases and hence the size decreases. That's why the size of Si (P) is smaller than Na (X), or we can say X is bigger in size than P.  Hence, the correct option is (i) X is bigger in size than P.
