Stable and Unstable Nuclei

What range does the strong nuclear force have?
0.5 fm to 3 fm
1 of 9
What does electromagnetic force affect in the nucleus?
It causes all the positively charged protons in the nucleus to repel.
2 of 9
What does gravitational force affect in the nucleus?
It causes all of the nucleons in the nucleus to attract each other because of mass
3 of 9
What range does the electromagnetic force act over?
Infinite.
4 of 9
Alpha decay happens in what type of atoms?
Atoms with more than 62 protons.
5 of 9
What do atoms emit when they undergo alpha decay?
An alpha particle. The mass number decreases by 4 and the proton number decreases by 2.
6 of 9
Beta-minus decay happens in what type of atoms?
Neutron-rich isotopes.
7 of 9
What do isotopes emit when they undergo beta-minus decay?
An electron and an antineutrino. The mass number stays the same but the proton number increases by one.
8 of 9
What type of decay would you expect in a nucleus with 14 nucleons, 6 of which are protons. Explain your answer.
Beta-minus decay as the nucleus is neutron rich.
