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.
(a) The given atom is, sodium (Na)
Atomic number of Na = 11
Number of electrons = 11
The electronic configuration of sodium atom is,
[tex]1s^22s^22p^63s^1[/tex]
(b) The given atom is, sulfur (S)
Atomic number of S = 16
Number of electrons = 16
The electronic configuration of sulfur atom is,
[tex]1s^22s^22p^63s^23p^4[/tex]
(c) The given atom is, magnesium (Mg)
Atomic number of Mg = 12
Number of electrons = 12
The electronic configuration of sulfur atom is,
[tex]1s^22s^22p^63s^2[/tex]
(d) The given atom is, neon (Ne)
