Question

which option describes the structure of the electron shells 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.

Explanation:

Carbon has an atomic number of 6. The first electron - shell (inner shell) can hold a maximum of 2 electrons and is considered complete when it has 2 electrons. The remaining 4 electrons go to the second (outer) shell, which can hold a maximum of 8 electrons, so it is incomplete.

Answer:

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