• The electro-negativities are unstable
• This is unstable because there are two protons
and only one neutron.
• The atomic weight, you add up all the masses of
the protons and neutrons and if you're above a
certain number it's [the nucleus is] radioactive. It
would have to have more protons than neutrons
to make it [the nucleus] heavier.
• You need the neutrons to shield the protons from
each other and if there is not enough of the
neutrons, and there are too many protons, and
they are all close together, then they start being
repelled.
• In like a stable atom you are supposed to have
equal numbers of protons and electrons so that
it's a neutral atom. Then if you have a lot of
electrons and not enough protons then it's gonna
be like a negatively charged particle. The excess
of negative charge is gonna interact with these
[the protons in the nucleus] and make this [the
nucleus] unstable in the fact that protons are
dealing with each other but also the fact that
outside [electrons] is sort of attracted to it.
