A monoatomic (X) ion has a charge of +3 the nucleus of the ion has a mass number of 45. the number of neutrons in the nucleus is 1.14 times that of number protons. Find out :
(a) Number of electrons in atom x.
(b) Number of electrons in `X^(3+)` ion.
(c) Configurations of X, `X^(3+)` and `X^(1+)` ion.
(d) Suggest which of the these `(X,X^(3+)` and `X^(+)`) are paramagentic
(e) the Total magnetic moment of `X^(+)` ion.

Explanation

(a) 21, (b) 18, (d) `X,X^+`, (e ) `sqrt(8)`. B.M,, .
