Question 3.39b

Postby Sydney Wu 2M » Tue Oct 18, 2016 5:36 pm

Can someone please explain why P is the central atom of the Lewis structure? It makes sense on paper because it looks nice, but doesn't K have the lower ionization energy?

Although K does have a lower ionization energy, in this case P is the central atom because it is capable of obtaining more than its octet of electrons. Potassium is too small to be able to hold more electrons than in their octet.
