?
What is the change in the nucleus in alpha decay?
2 neutrons and 2 protons are lost
1 of 25
What is the change in the nucleus in beta decay?
A neutron becomes a proton
2 of 25
What is the particle emitted in alpha decay?
2 protons & 2 neutrons are emitted
3 of 25
What is the particle emitted in beta decay?
an electron is created in the nucleus and emitted instantly
4 of 25
What happens if an atom loses or gains electrons?
It is called an ion
5 of 25
What are atoms of the same element, but with different numbers of neutrons called?
isotopes
6 of 25
What is the atomic number?
The number of protons
7 of 25
What is the mass number?
The number of protons + neutrons
8 of 25
Name two sources of background radiation.
Nuclear Power plants and Rocks
9 of 25
What was the "plum pudding" model of the atom?
It's electrons were in spheres of positive charge randomly scattered
10 of 25
What was Rutherford's alpha-particle scattering experiment?
He fired alpha particles at thin gold foil and measured it with a gieger counter
11 of 25
Why did most particles pass through the foil?
Because atoms are mainly made up of empty space
12 of 25
What does this suggest about the nucleus?
It has a positive charge
13 of 25
What is Nuclear Fission?
splitting of a nucleus
14 of 25
If you answered false to the above question, what isotopes are the most common use in Nuclear reactors?
I answered true
15 of 25
What is "enriched" uranium?
2-3% Uranium-235
16 of 25
What is "enriched" Carbon?
It doesn't exist
17 of 25
What must be absorbed for fission to occur?
An neutron
18 of 25
What is a "chain reaction"?
Many fission reactions
19 of 25
What is nuclear fusion?
Joining of 2 nuclei
20 of 25
What is released during fusion?
Energy
21 of 25
How are nuclei contained in a fusion reactor?
A magnetic field
22 of 25
Why does one of these reactions need a very high temperature?
Because the nuclei need a lot of energy to crash
23 of 25
By what process is energy released in stars?
Nuclear Fusion
24 of 25
What happens for fission to occur?
The neutron must be absorbed by a neucleus
