E=mc^2 Rap

atom is the basic unit of matter and
all things alive or not are made of  ’em
they’re what you get when you breakdown anything
so that in the universe everything is everything
made up of 3 different parts
at the center is the nucleus, it’s the heart
Inside are protons, positively charged
each one of those Ps wants to live large
gotta be stuck together by a neutron you see
no charge, got the nuclear strong force G
if it weren’t for these guys, atoms be buggin’
and then there’d be no matter, there wouldn’t be nothin’
outside the nucleus is the third part
but don’t think it’s the end, it’s only the start
electrons are negative, attracted to the Ps
opposites attract in all of chemistry
inside the atom, protons call the shots
number of protons you have, tells ya the element ya got
need one neutron for every P
but as elements get heavy, more neutrons ya need
Uranium 235, 92 protons
subtract and get 143 neutrons
repelling protons, unstable dude
143 neutrons aint enough glue
neutron from outside hits it like a bullet
two smaller atoms form, 3 neutrons, that’s not it
chain reaction, nuclear fission comes alive
lots of neutrons slam U-235
parts of the whole lose mass, so somthin’ is missin’
must be binding energy, Einstein was guessin
he turned out to be right so don’t be scared
mass converts to energy cuz E=mc2
nuclear energy is mighty strong
when released, lasts really long
c is the speed of light you see
square it and you get 9 with 16 zeros B
that small change in mass you times it by
to get lots of energy as heat, that aint no lie
put it in a bomb, destroy a city
or power a plant to make electricity
