They have the same charges but different masses
They both have 0 mass and a negative charge
They are identical except for charge: positrons have a -1 charge and a electrons have a +1 charge
They are identical except for charge: electrons have a -1 charge and a positrons have a +1 charge
What do controls rods do in a nuclear reactor?
Absorb neutrons from the fission reaction, allowing the rate of reaction to be controlled.
Absorb neutrons from the fusion reaction, allowing the rate of reaction to be controlled.
Absorb protons from the fission reaction, allowing the rate of reaction to be controlled.
They have no function in relation to a nuclear reactor.
All of the following are true of alpha particles EXCEPT
They have the same composition as helium nuclei
They carry a charge of 2+
They are more penetrating than beta particles.
They are represented by the symbol 42He

the energy for the radiation
the penetrating ability of the radiation
the ionizing ability of the radiation
the chemical properties of the radiation
Element 119 is a man-made element with a half life of .4500 seconds. Only 3,000 atoms of the element were created in tests. How many atoms were left after 1.8 seconds?
375 atoms were left
187.5 atoms were left
93.75 atoms were left
.028125 atoms were left
The Cesium-131 nuclide has a half-life of 30 years. After 150 years, about 40 grams remain. The original mass of the Cesium-131 sample is:
1.25 grams
1280 grams
640 grams
4.1 grams
Geologists use the decay of Potassium-40 in volcanic rocks to determine their age. Potassium-40 has a half life of 1.26 x 109 years, so it can be used to date very old rocks. If a sample rock 2.52 x 109 years old contains 2.73 x 10-7 grams of potassium-40 today, how much Potassium-40 was originally present in the rock?
1.09 x 10-6 grams
6.85 x 10-8 grams
2 half lives
160 grams of Potassium-40
