Forces and Nuclear Particle Interactions

Front

What is the Z value in nuclear notation?

Back

The Z value represents the atomic number, which is the number of protons in the nucleus of an atom.

Front

What is the mass number (A) in nuclear notation?

Back

The mass number (A) is the total number of protons and neutrons in the nucleus of an atom.

Front

How do you calculate the number of neutrons in an isotope?

Back

Number of neutrons = Mass number (A) - Atomic number (Z).

Front

What is U-235?

Back

U-235 is an isotope of uranium with 92 protons and 143 neutrons, commonly used as fuel in nuclear reactors.

Front

What is gamma decay?

Back

Gamma decay is a type of radioactive decay where an unstable nucleus releases energy in the form of gamma rays without changing its number of protons or neutrons.

Front

What is a daughter isotope?

Back

A daughter isotope is the product of the decay of a parent isotope.

Front

What particle is responsible for carrying the gravitational force?

Back

The graviton is the hypothetical particle that mediates the force of gravity.

Front

What are the four fundamental forces of nature?

Back

The four fundamental forces are gravitational, electromagnetic, strong nuclear, and weak nuclear forces.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (electron or positron) is emitted from an atomic nucleus.

Front

Which force is responsible for beta decay?

Back

The weak nuclear force is responsible for beta decay.
