Back

\( _{83}^{205}Bi \)

Front

Which process occurs naturally in the centre of stars like the Sun?

Back

Fusion

Front

Has the lowest penetrating power. Can only penetrate 0.05 mm into the body and can be stopped by the skin.

Back

Alpha

Front

Which type of nuclear radiation is being emitted here?

Back

Beta

Front

What is the process of combining two light atomic nuclei to form a heavier nucleus called?

Back

Fusion

Front

What type of radiation is emitted during beta decay?

Back

Beta particles (electrons or positrons)

Front

What is the primary difference between fission and fusion?

Back

Fission splits heavy nuclei; fusion combines light nuclei.

Front

What is the penetrating power of gamma radiation compared to alpha and beta radiation?

Back

Gamma radiation has the highest penetrating power.

Front

What is the main fuel for nuclear fusion in stars?

Back

Hydrogen isotopes (like deuterium and tritium)
