Nuclear Equations

Front

What is a nuclear equation?

Back

A nuclear equation represents a nuclear reaction, showing the transformation of one element into another, including the emission or absorption of particles.

What does U-238 decay into?

Back

U-238 decays into Th-234 through alpha decay.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (2 protons and 2 neutrons), resulting in a new element.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a neutron is transformed into a proton, emitting a beta particle (electron) and an antineutrino.

Front

How do you balance a nuclear equation?

Back

To balance a nuclear equation, ensure that the sum of atomic numbers and mass numbers is equal on both sides of the equation.

Front

What is the significance of the atomic number in nuclear equations?

Back

The atomic number determines the element's identity and its position in the periodic table; it must be conserved in nuclear reactions.

Front

What is the significance of the mass number in nuclear equations?

Back

The mass number represents the total number of protons and neutrons in an atom's nucleus; it must also be conserved in nuclear reactions.

What is the product of the decay of Carbon-14?

Back

Carbon-14 decays into Nitrogen-14 through beta decay.

Front

What is the role of helium in nuclear reactions?

Back

Helium is often produced as an alpha particle in nuclear reactions, representing the emission of two protons and two neutrons.

Front

What is a decay series?

Back

A decay series is a sequence of radioactive decay processes that an unstable nucleus undergoes until it reaches a stable state.
