When an atom emits an alpha particle, what happens to its mass number?*1 pointincreases by 2decreases by 2increases by 4decreases by 4
Question
Solution 1
When an atom emits an alpha particle, its mass number decreases by 4. This is because an alpha particle is composed of 2 protons and 2 neutrons, which together account for a decrease of 4 in the mass number of the original atom.
