“Atoms of the same element with different mass numbers”
3 of 12
Relative Atomic Mass
“Mass of a single atom scaled to 12C exactly”
4 of 12
Relative Molecular Mass
“Mass of a single molecule scaled to 12C exactly”
5 of 12
Cation
“Atom or molecule that has lost an electron"
6 of 12
Anion
“Atom or molecule that has gained and electron"
7 of 12
Fusion Reactions
2 nuclei joining / fusing together to make a single heavier nucleus. Require incredibly high temperature and pressure.
8 of 12
Fission Reactions
Involve a nucleus breaking apart to form 2 smaller nuclei. Usually involve atoms with large nuclei such as the Lanthanides and Actinides. They can produce a, B and y emissions.
