Why do scientists do experiments
to prove/disprove/extend a theory
What do A Z X represent in an atom
A - mass number Z - proton number X - symbol
what are isotopes
Isotopes are atoms that contain the same number of protons but a different number of protons.
Charge of a nucleus
number of protons x proton charge
Mass of nucleus
number of nucleons x mass of nucleons
What is specific charge
charge to mass ratio
Specific charge (nucleus)
(number of electrons x electron charge)/(number of nucleons x nucleon charge)
Specific charge (ion)
(electrons x electron charge)/(nucleons x nucleon charge) + (proton number - difference in electron count) x mass of electron.
