what is this chart? I just don’t understand these numbers and letters are making me dizzy man first look at the atom, aint no big thing basic unit of matter, a part of everything inside float around the positive protons along with all the neutral neutrons protons by themselves get an atomic number ok now I get it, cool as a cucumber atomic number is the number on top of those symbols, seems like they never stop a symbol of a pure chemical it represents or letters that represent an element that’s all I need to know, yeah I got I right but that’s just the start man, don’t put up a fight nest thing is pretty fresh man this is the bomb floatin’ outside is an electron it gets real lonely when it’s only one needs a friend to make a pair so it can have some fun four pairs are even better to make a whole group of eight now that there are eight, each one can feel really great that’s four pairs times two and it’s called the octet rule that’s easy math man I aint no dang fool that’s how an electron loves to behave can exist as a particle, can also be a wave there’s another number we gotta learn in class bigger than the atomic number, it’s called the atomic mass atomic mass is equal to about two times the protons a combo of equal parts protons and neutrons in the heavy elements there might be some trouble atomic mass can weigh a lot more than double lots of energy amongst all those extra neutrons push together repelling positive protons that single element can contain isotopes different atomic masses, man that’s pretty dope emits alpha, beta or gamma rays process called radio-active decay when these atoms split you’d better look out nuclear energy makes me wanna shout instead of fossil fuels, creates electricity keep it out of bombs, like Obama use diplomacy that’s what Einstein showed when he discovered this the power of the atom you’d better not dis it’s got binding energy it really wants to share even when at rest its energy E=mc2 that’s enough background you need to know now got to read the table, I’m gonna show you how gonna have to come in the very next song rap’s goin’ on and on and gettin’ too long
