Question

Write the electronic configuration of sodium ion and magnesium ion​

Answer 1

Answer:

What is the electronic configuration for sodium ion?

The electronic configuration is termed as the distribution of electrons of an atom in the orbitals. The gaining or losing of electrons from an atom is known as ion.

Sodium

Sodium is a vital element in the periodic table. Given below are the properties of sodium.

Atomic Number

The atomic number of Sodium is 11

The total number of electrons is 11 in the sodium atom.

Electronic configuration

The electronic configuration of sodium is 2, 8, 1

We can represent the electronic configuration as 1s2 2s2 2p6 3s1

Sodium-ion

In sodium-ion the Sodium atom loses one electron from the atom.

Electronic configuration

The electronic configuration of sodium ion becomes 2,8 on losing one electron.

We can represent the electronic configuration as 1s2 2s2 2p6

Hence, the electronic configuration of sodium ion is 1s2 2s2 2p6
