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,
\(1s^22s^22p^63s^1\)
