The electronic configuration of iodine is

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 4p⁶, 4d¹⁰, and 5s², 5p⁵

Iodine has 53 electrons according to its atomic number, which is 53. These electrons are distributed across various shells, subshells, and orbitals according to the electronic configuration.

Explanation

Let’s divide the electronic configuration  into its orbitals, suborbitals, and shells:

first shell

The 1s subshell is the only subshell in the first shell (n=1). It has two electrons in it.

second shell

The 2s and 2p subshells are present in the second shell (n=2).

There are

• two electrons in the 2s subshell
• and six in the 2p subshell.

third shell

The 3s, 3p, and 3d subshells make up the third shell (n=3).

There are

• two electrons in the 3s subshell,
• six in the 3p subshell,
• and ten in the 3d subshell.

fourth shell

The subshells 4s, 4p, and 4d are found in the fourth shell (n=4).

There are

• two electrons in the 4s subshell,
• six in the 4p subshell,
• and ten in the 4d subshell.

fifth shell

Moving on,

• we have the 5s and 5p subshells for the fifth shell (n=5).
• While the 5p subshell has five electrons, the 5s subshell only has only two.
