part b
what is the symbol for a gamma ray?
express your answer as a chemical expression.

Explanation:

Part A

• Option 1: Gamma radiation is high - energy electromagnetic radiation in the form of photons.
• Option 2: Proton to neutron conversion is positron emission, not gamma radiation.
• Option 3: Emitting a particle with 2 protons and 2 neutrons is alpha decay.
• Option 4: Emitting an electron is beta - minus decay.

So the correct option is the first one.

Step1: Recall gamma ray symbol

Gamma rays are represented as $\gamma$ in nuclear and chemical notation.

Answer:

A. Gamma radiation is a type of electromagnetic radiation that is essentially a high energy photon.
