I wasn’t sure that silicon still has only 1 neutron per proton, so I had to check as well.
Looking again at the periodic table it seems like some elements before and after silicon already have an extra neutron per proton (even the majority of lithium has an extra neutron!) - gotta keep the nucleus together, right?
By weight it’s almost fifty-fifty (28:32).
Yes, I had to check before making the comment because I had a hunch it would be close.
