Answer : The correct electronic configuration of sodium atom is,


1s^22s^22p^63s^1

Explanation :

Electronic configuration : It is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom are determined by the electronic configuration.

Atomic number : It is defined as the number of electrons or number of protons present in a neutral atom.

The given atom is, sodium (Na)

Sodium is the 11th element which belong to period 1.

The electronic configuration of sodium atom is,
