A pupil has drawn the electronic structure of fluorine and the diagram is shown below. However, mistakes have been made. State three mistakes that have been made.

The first shell can only hold 2 electrons, but the pupil placed in 8 electrons.

The second shell can hold up to 8 electrons, but the pupil only placed in 2 electrons.

Flourine only has 9 total electrons, yet there are 10 electrons in the diagram.

Explanation:

In the Fluorine atom there are 2 electrons in the innermost shell and 7 i the outer shell.

i think that the answer is c
