Particles and Quantum physics Flashcards
1
Q
Why do scientists do experiments
A
to prove/disprove/extend a theory
2
Q
What do A Z X represent in an atom
A
A - mass number Z - proton number X - symbol
3
Q
what are isotopes
A
Isotopes are atoms that contain the same number of protons but a different number of protons.
4
Q
Charge of a nucleus
A
number of protons x proton charge
5
Q
Mass of nucleus
A
number of nucleons x mass of nucleons
6
Q
What is specific charge
A
charge to mass ratio
7
Q
Specific charge (nucleus)
A
(number of electrons x electron charge)/(number of nucleons x nucleon charge)
8
Q
Specific charge (ion)
A
(electrons x electron charge)/(nucleons x nucleon charge) + (proton number - difference in electron count) x mass of electron.
