Nuclear Symbols

Match the symbol to each type of radiation

• alpha particle

• 
• gamma ray

• 
• beta particle

• ⁰₀γ

Match the radioactive decay particle with its description.

• alpha particle

• an electron

• beta particle

• wave of energy

• gamma ray

• A helium nucleus (2 p⁺, 2 n⁰)

Which symbol(s) represent an alpha particle?

• yellow

• blue

• red

Which symbol(s) represent an beta particle?

• yellow

• blue

• red

What is a beta particle made of?

• One proton

• A helium particle

• One electron

• One proton and one neutron

During beta decay, a neutron in the nucleus of an atom is transformed into:

• A proton and emits a gamma ray

• A proton and emits an electron

• An alpha particle

• A proton and a neutron

When a nucleus undergoes nuclear decay by gamma rays, the atomic number of the element....

• remains the same
•   decreases by one.
• increases by one.
• increases by two.

What is likely to happen to unstable nuclei with too many, or too few, neutrons?

• They will decay by emitting radiation.

• They will loose all their electrons.

• They will bond with other atoms.
