Isotopes and Nuclear Radiation

beta particle

For every emitted, a neutron in the nucleus has turned into a proton.

Gamma rays

are waves of electromagnetic radiation released by the nucleus.

Isotopes

are different forms of the same element.

mass numbers

They can also release neutrons when they decay, as they rebalance their atomic and .

Radioactive substances

spit out one or more types of ionising radiation from their nucleus- the ones you need to know are alpha, beta and gamma radiation.

particle

A a- is two neutrons and two protons.

Alpha particles

are helium nuclei.

Alpha radiation

is when an alpha particle is emitted from the nucleus.

Beta particles

have virtually no mass and a charge of- 1.

Gamma rays

are EM waves with a short wavelength.

Isotopes

are atoms with same number of protons different number of neutrons.

Beta particles

are high- speed electrons.

beta particles

A(n) , is simply a fast- moving electron released by the nucleus.
