The electronic configurations of four particles A, B, C and D given below:

A 2, 8, 8
B 2, 8, 2
C 2, 6
D 2, 8

Which electronic configuration represents:
(i) magnesium atom?
(ii) oxygen atom?
(iii) sodium ion
(iv) chloride ion?

Solution

(i) Electronic configuration of particle B represents magnesium atom because its atomic number is 12.

(ii) Electronic configuration of particle C represents oxygen atom because its atomic number is 8.

(iii) Electronic configuration of particle D represents sodium ion. Atomic number of sodium is 11 and it loses one electron to stabilise and forms sodium ion containing 10 electrons.

(iv) Electronic configuration of particle A represents chloride ion. Atomic number of Chlorine is 17 and it gains one electron to stabilise and forms chloride ion containing 18 electrons.

  Is there an error in this question or solution?
