Question

Write the electronic configuration of boron.

Answer 1

Definition of electronic configuration.

The arrangement of electrons in various energy levels of an element is called electronic configuration.

The maximum number of electrons which can be accommodated in any shell of an atom is given by 2n^2.

Atomic number of boron = 5

Electronic configuration = 2,3

K- shell = 2 electrons, L-shell = 3 electrons.
