Natiijada casharka
I can use a nuclear equation to represent alpha and beta decays, and describe the particles involved.
Muuji qoraalka
A nuclear equation shows the particles in a nuclear decay, including the electric charge and mass number of each one.
An alpha particle consists of two protons and two neutrons, has a mass of 4 and charge of +2.
The protons and neutrons in an alpha particle are held together very strongly.
After an alpha or beta decay, a nucleus usually emits some gamma radiation.
A beta particle is an electron emitted at a high speed from a nucleus, its mass is close to zero and charge of –1.
