Question

a) Explain the formation of Magnesium chloride with the help of electron dot structure
(At number Mg = 12. CI= 17)


b) A non metal X exists in two different forms Y and Z Y is the hardest natural
substance while Z is good conductor of electricity. Identify the nonmetal X​

Answer 1

Answer:

a) The electronic configuration of Mg is 2,8,2. Hence, magnesium needs to loose 2 electrons to become stable. Electronic configuration of chlorine is 2,8,7. Hence, chlorine needs to gain 1 electron to become stable.

b) The non-metal X is carbon. The hardest natural substance y is diamond and Z which is a good conductor of electricity is graphite.
