nuclear chemistry Flashcards
1
Q
radioactive decay
A
involves changes in the nuclei of atoms. unstable nuclei can become more stable nuclei by giving alpha, beta, gamma radiation
2
Q
alpha radiation
A
consists of 2 protons and 2 neutrons which carry double positive charge - attracted towards negatively charged plate
3
Q
beta radiation
A
electrons ejected from nucleus of atom. attracted towards positively charged plate
4
Q
gamma radiation
A
electromagnetic waves emitted within nucleus. not deflected by electrical field
5
Q
half life
A
time taken for half of nuclei of particular isotope to decay
