Answer:
E
Explanation:
To know what will happen, we need to know
the total number of electrons the element have.
This can be calculated by adding all the electrons together
That would be 2 + 2 + 6 + 2 + 4 = 16
This shows that the element is sulphur.
Now using the KLMN electronic configuration, sulphur has the shells 2,8,6 meaning there are 2 extra electrons needed for octet configuration to be achieved.
This makes option E the correct answer to the question
