What is ionisation?
Radiation that causes atoms to become ionised/ ions (removes an electron from the atom to make it positive).

Finish the lyric from 'Bye Bye Bye' by NSYNC:
Don't wanna be a fool for you
Just another player in your game for two
You may hate me, but ....
It ain't no lie
Baby, bye, bye, bye (bye, bye)

Calculate the number of neutrons in oxygen-16.
Neutrons = mass - protons = 16 - 8 = 8 neutrons

Explain the changes that occur in the parent nucleus during alpha decay.
Loss of 2 protons and 2 neutrons (an alpha particle)
400
How are an alpha particle and a helium atom different?
What is a helium atom has electrons, but an alpha particle does not (hence the +2 charge)
