Question

PLEASE TELL ME THE ANSWERS OF THESE FOLLOWING QUESTIONS.

(e) Group whose elements have zero valency.
(f) A covalent compound formed by an element in Period
2 and a halogen.
(g) Non-metallic element present in Period 3 of Groups
15 and 16.
(h) An electrovalent compound formed by an alkaline
earth metal and a halogen.
(i) Bridge elements of Period 3 of Group 1, 2 and 3.
(1) Alkali metal in Period 3 that dissolves in water giving
a strong alkali.
(k) Typical elements of Groups 14 and 15.
(1) Alkaline earth metal in Period 3.​

Answer 1

Answer:

HEY MATE!!

e) Noble group.

f) Nitrogen is a non metal of 2nd period andhalogen is chlorine. So a covalent compound is NCl3 or nitrogen trichloride.

g) 15- Phosphorus

16- Sulphur

h) MgF2

i) The elements of group 2 are called bridge elements because these elements are related to the next group which are placed diagonally to it hence forming a bridge that is why they are called bridge elements. This elements are li, be, b, c, n, o, f, ne.

1) sodium

• The alkali metal in period 3 is sodium. It dissolves in water to give a strong alkali NaOH

k) Group 14 is called the carbon group. This groupcontains two metalloids: silicon and germanium. Carbon is a nonmetal, and the remainingelements in this group are metals. Group 15 is called the nitrogen group

1) Alkaline earth metal in period 3.

• Magnesium is the alkaline earth metal present in period 3 of the periodic table.
