Question

what information does the electronic configuration of an atom provide?

Answer 1

Electronic configuration of an atom provides the following information:
☆No. Of valency electrons in the atoms/Determines the no. Of shells in the atom.
☆ Determines the valency of the atom of an element.

Answer 2

● The distribution of elements in shells, subshells and orbital in an atom is known as electronic configuration.

● It provides the information of position of an electron in the space at atom.

● The distribution of elements in various atomic orbitals provides on understanding of electronic behaviour of the atom and in turn its reactivity.

● The short hand notation is shown as

${nl}^{x}$

Where 'n' denotes principle quantum number.

'l' denotes the angular momentum of quantum number.

'x' denotes the number.
