Subject: Why isn't everything made of neutrons?

I have been told the most probable place to find a 1s electron in 
an atom is at the nucleus. 

What forces are involved in neutron formation and why doesn't it 
happen all the time from the attraction from the opposite 
charges?

Although there are other forces involved in the heart of the atom 
I can't see why they would be responsible for the repulsion 
between electron and neutron.

I am asking as everyone who I've tried to ask seems to avoid the 
question, as if its a foregone conclusion.
