Atom and radiation

HideShow resource information
Isotopes
are atoms with the same number of protons and different number of neutrons
1 of 8
Specific charge
It's charge divided by its mass
2 of 8
Electron
1) Has a smaller mass than the proton or the neutron. 2) Is negatively charged. 3) Is part of the Lepton family 4) is affected by the electrostatic force
3 of 8
Proton
1) Made from 2 up (u) quarks and 1 down (d) quark. 2) Is positively charged. 3) Is part of the Baryon family 4) is affected by the strong and weak force
4 of 8
Neutron
1) Is made from 1 up (U) and 2 down (d) quarks. 2) Has a no charge 3) Is a Baryon 4) Is affected by the strong and weak force
5 of 8
Alpha radiation
Consists of alpha particles which each comprise two protons and two neutrons. Its proton number is 2 and its mass number is 4
6 of 8
Beta radiation
consists of fast moving electron. Its charge is equal and opposite of that of the proton and its mass is much smaller than the protons mass. It also produces a nuetino or an antinuetrino
7 of 8
Gamma radiation
Is electromagnetic radiation emitted by an unstable nucleus. It can pass through thick metal plates. It has no mass and no charge. It is emitted by a nucleus with too much energy, following beta or alpha emission
