Which option describes the structure of the electron shells

Question

in a neutral carbon atom? (1 point)
The inner shell is incomplete with three electrons. The
outer shell is incomplete with three electrons.
The inner shell is complete with three electrons. The
outer shell is incomplete with three electrons.
The inner shell is complete with four electrons. The
outer shell is incomplete with two electrons.
The inner shell is complete with two electrons. The
outer shell is incomplete with four electrons.

Answer 1

In a neutral carbon atom, there are 6 electrons. The configuration of these electrons is as follows:

• The inner shell (1st shell) can hold a maximum of 2 electrons, and for carbon, it is complete with 2 electrons.
• The outer shell (2nd shell) can hold a maximum of 8 electrons, and in carbon, it has 4 electrons.

Therefore, the correct option that describes the structure of the electron shells in a neutral carbon atom is:

The inner shell is complete with two electrons. The outer shell is incomplete with four electrons.
