So I will match them but by words so if necessary you will have to do the number letter pairing.. kool:
protons plus neutron = atomic mass
proton number = atomic number
detects radiation = Geiger Counter
fixed shape = solid
neutral charge = neutron
positive charge = proton
occupies the whole container = gas
measures the intensity of radiation = photographic film
smallest particle to retain characteristics = atom
negative charge = electron
Hope this helps and doesn't leave you with too much work
