Question
Write down the electronic configuration of the following
- 2713X,
- 3517Y.
Write down the number of electrons in X and neutrons in Y and the formula of the compound formed by X and Y.[XY3]
Solution
Electronic configuration of:
(1) 2713X number of electrons = 13
Distribution of elecrtrons in different ordits
13 = [2, 8, 3]
K L M
Number of neutrons in Y
= A − Z = 35 − 17 = 18
(2) 3517Y number of electrons = 17
Distribution of electrons in different orbits
17 = [2, 8, 7]
K L M
Formula of compound formed is
