Question

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.

Fl atomic number: 9
Fl atomic mass: 10

(ps i have two of these but can’t figure out the last)

Answer 1

• The number of electrons in the orbit is wrong they have to be 9 and not 10
• since flourine is in group 7 the number of electrons in the outer most shell has to be 7 and not 2
• the first shell has 8 instead of 2 electrons

I hope this helps
