- 1Which particles are in the atom?The proton, the neutron and the electron.
- 2Describe the charge and mass of the proton, neutron and electron in SI units and relative units:Proton: +1.6 x 10-19 1.67 x 10-27
Neutron: =O 1.67 x 10-27
Electron: - 1.6 x 10-19 9.11 x 10-31 - 3How do you calculate specific charge?Charge divided by mass....
- 4Define an isotope:An atom with the same number of protons and a different number of neutrons.
- 5What is the strong nuclear force, and how does it keep the nucleus stable?It holds the protons and neutrons together, and overcomes electrostatic force.
It's range is 3 - 4 fm (Femtometers) - 6Which force is attractive up top 3 - 4 fm, and repulsive under 0.5 fm?The strong nuclear force.
- 7Describe alpha and beta decay:A particle loses 2 protons and 2 neutrons.
These form an alpha particle. - 8Describe beta decay:A particle gains a proton as a neutron changes into a proton. The mass number stays the same. An electron and anti-neutrino are emitted.
