Note that for shell diagrams of ions, you have to get the right number of electrons first!
p19.
1. Draw a shell diagram for each of the
following:
a. 23Na 11p
and 12n 2e) 8e)1e
b. 14N 7p and 7n 2e)
5e
c. 38Ar 18p and 20 n 2e) 8e ) 8e
d. 35Cl
17p
and 18 n 2e) 8e ) 7e
e. 36Cl -1 protons – charge = electrons
17 – (-1) = 18
