- 1What are the three sub-atomic particles of an atom?1) proton
2) neutron
3) electrons - 2a) relative mass b) location c) charge -of each sub atomic particle?proton: a) 1 ; b) nucleus ; c) +1
neutron: a) 1 ; b) nucleus ; c) 0
electron: a) 0 ; b) shells ; c) -1 - 3Atoms contain an equal number of ____ and _____, so carry no overall _____.Atoms contain an equal number of protons and electrons, so carry no overall charge.
- 4atomic number = ...atomic number = number of protons (=number of electrons)
- 5mass number = ...mass number = number of protons + neutrons
- 6How do you work out the number of neutrons in an atom?mass number - atomic number
- 7Lead has an atomic number of 82, and a mass number of 207. Work out the number of: a) protons b) electrons c) neutronsa) protons = atomic number = 82
b) electrons = atomic number = 82
c) neutrons = mass no. - atomic no. = 125
