Draw a Bohr diagram of the protons and electrons in each of the following.

a) an atom of magnesium

Do I draw this with 19 atoms surrounding the shell of Magnesium around?

9 answers

I mean 12 atoms.

Yes 13
But the 12 electrons are in different shells.

I mean 12 not 13 of course

13?

Will the REAL Damon please stand up.

Thanks for the clarification

2 s electrons in the first shell. That fills it with 2

2 s and 6 p electrons in the second shell. That fills it with 8

The last 2 s electrons are in the third shell

LOL - That confused me too :)

Thank you very much sir
