Front

What type of decay involves the emission of an alpha particle?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (2 protons and 2 neutrons) and transforms into a different element.

Front

What is the process called when two light nuclei combine to form a heavier nucleus, releasing a large amount of energy?

Back

Nuclear Fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What are subatomic particles that have no charge?

Back

Neutrons are subatomic particles found in the nucleus of an atom that have no electric charge.

Front

Does increasing temperature increase the kinetic energy of particles?

Back

True. Increasing temperature raises the kinetic energy of particles, leading to more frequent and energetic collisions.

Front

In a chemical reaction, what do we call everything to the right of the arrow?

Back

Products are the substances formed as a result of a chemical reaction, located to the right of the reaction arrow.

Front

What is the term for a reaction that involves the splitting of a heavy nucleus into lighter nuclei?

Back

Nuclear Fission is the process in which a heavy atomic nucleus splits into two or more lighter nuclei, accompanied by the release of energy.

Front

What is the charge of protons?

Back

Protons have a positive charge.

Front

What is the role of catalysts in chemical reactions?

Back

Catalysts are substances that increase the rate of a chemical reaction without being consumed in the process.

Front

What is the law that states that mass is neither created nor destroyed in a chemical reaction?

Back

The Law of Conservation of Mass states that in a closed system, the total mass of reactants equals the total mass of products.

Front

What is the term for the energy required to initiate a chemical reaction?

Back

Activation Energy is the minimum energy required to start a chemical reaction.
