Question

(a) Elements X, Y and Z have atomic numbers 6, 9 and
12 respectively. Which one :
(i) forms an anion, (ii) forms a cation,
(b) State the type of bond between Y and Z and gets
molecular formula.
Taking MgCl2 as an example of electrovalent bond, CCI,
as a covalent bond, give a difference between electrovalent
and covalent bonds.
Potassium chloride is an electrovalent comnound while​

Answer 1

Answer:

X and y will form anion and z will form cation.

2. Molecular formula = MgF2

3. Electrovalent or ionic bonds formed by ions with the help of electro static force of attraction but covalent bonds formed by sharing of electrons.

Answer 2

Answer:

X is carbon

Y is fluorine

Z is magnesium.

Magnesium..... That is...... Z is a cation.

Flourine........ That is.........Y is an anion.

Carbon exhibits the valencies from +4 to -4
