CP6F Radioactive decay Flashcards
1
Q
What happens in the process of beta plus decay
A
A proton turns into a neutron and a positron (in order to conserve charge)
2
Q
What is the process called when a neutron changes into a proton and an electron
A
Beta minus decay
3
Q
When alpha decay occurs, what happens to the atomic number and mass number of the atom
A
The atomic number decreases by 2
The mass number decreases by 4
A new element is made
4
Q
What effect does beta minus decay have on the mass number and atomic number of a atom
A
The mass number stays the same as the total number of neutrons and protons hasn’t changed
The atomic number increases since there is one more proton
