Nuclear Equations

What is nuclear radiation?

• The process of splitting an atom into two smaller atoms.

• The emission of particles or electromagnetic waves from the nucleus of an unstable atom as it decays.

• The absorption of energy by an atom causing it to become unstable.

• The release of heat energy from a chemical reaction.

What is a beta particle?

• A high-energy, high-speed electron or positron emitted during beta decay.

• A type of alpha particle that is less stable.

• A neutron that is released during nuclear fission.

• A photon emitted during radioactive decay.

How does beta decay affect the atomic number of an element?

• Beta decay decreases the atomic number by 1.

• Beta decay does not affect the atomic number.

• Beta decay increases the atomic number by 1.

• Beta decay increases the atomic number by 2.

What is the symbol for gamma radiation?

• α

• β

• γ

• δ

How does alpha decay affect the atomic number of an element?

• Alpha decay increases the atomic number by 2.

• Alpha decay decreases the atomic number by 1.

• Alpha decay decreases the atomic number by 2.

• Alpha decay does not affect the atomic number.

What is the symbol for alpha radiation?

What is the charge of a beta particle?

• 0

• -1 (for electrons)

• +1 (for positrons)

• +2

What is gamma radiation?

• A form of electromagnetic radiation of high frequency and energy, emitted from the nucleus during radioactive decay.

• A type of particle radiation consisting of high-energy electrons.

• A form of radiation that is primarily associated with chemical reactions.

• A low-frequency radiation used in medical imaging.

What is the mass number of an alpha particle?

• 2

• 4

• 6

What is the significance of gamma rays in nuclear reactions?

• Gamma rays carry away excess energy from a nucleus after a decay process, without changing the atomic number or mass number.

• Gamma rays are responsible for the fusion of atomic nuclei.

• Gamma rays increase the mass number of the nucleus during decay.

• Gamma rays are used to stabilize the atomic number of elements.
