16. (Ipt ea) Matching: Use the following terms to match to the descriptions. You may use a term more than once if needed (but only one per blank). Terms: a. Has no mass and no charge b) Is represented by 4 He c) Is attracted to a positively charged plate d) Is emitted when a neutron decomposes into a proton e) Is stopped by clothing or skin Positron 2. Neutron 3. Proton 4 Alpha radiation 5 Beta radiation 6. Gamma radiatio f) Fastest traveling form of radiation -g) Is the same mass but opposite charge compared to an electron h) Form of radiation with the greatest mass

Explanation / Answer

16)
a) The nuclear particle with no mass and no charge is actually neutrino.
b) 42 He is represented by Alpha radiation.
c) Electron is attracted to positively charged plate, positron and proton have positive charges
while neutron has no charge hence negatively charged electron is attracted to positive plate.
d) 10 n ---------> 11H + 0-1e
electron (0-1e ) when neutron decomposes to proton.
e) Alpha radiation is stopped by skin or clothing
f) Gamma radiation is the fastest travelling form of radiation since they have photons which travel with
the speed of light.
g) Positron has the same mass but opposite charge compared to an electron.
h) Alpha radiation is the form of radiation with the greatest mass since it emits helium.
