?
What part of the atom does radioactivity involve?
Nucleus
1 of 11
What type of atom does radioactivity involve?
Isotopes
2 of 11
What are isotpes?
atoms of the same element with the same no. of protons(and electrons) but a different no. of neutrons.
3 of 11
What do electrons absorb?
Electromagnetic Radiation
4 of 11
What happens when electrons absorb elctromagnetic radiation?
If an atom absorbs elctromagnetic radiation the elctron can move to a higher enegy level.
5 of 11
What is the overall charge of the nucleus?
Positive (due to the protons)
6 of 11
What are the properties of a radioactive isotope?
they have an unstable nucleus - to become stable the nucleus gives out radiation
7 of 11
What is radioactive decay?
It is a completely random process where the nucleus of a radioactive isoptopes give out radiation.
8 of 11
Alpha Particles
Alpha particles are the same as the nucleus of a helium atom. 2 neutrons and 2 protons
9 of 11
Beta Particle
An elctron formed when a neutron splits into a proton and an electron.
10 of 11
Gamma Rays
A type of electromagnetic radiation from the nucleus. A wave.
