Nuclear Chemistry: Balancing

Front

What is alpha decay?

Back

A type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of 2 protons and 2 neutrons, resulting in a new element.

Front

What is beta decay?

Back

A type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus, transforming a neutron into a proton or vice versa.

Front

What is gamma emission?

Back

The release of gamma rays from a radioactive nucleus, which does not change the number of protons or neutrons but releases energy.

Front

What is an alpha particle?

Back

A particle consisting of 2 protons and 2 neutrons, identical to a helium nucleus, emitted during alpha decay.

Front

What is a beta particle?

Back

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

Front

What is a neutron?

Back

A subatomic particle found in the nucleus of an atom, with no electric charge and a mass slightly greater than that of a proton.

Front

How do you balance a nuclear equation?

Back

Ensure that the sum of atomic numbers and mass numbers is equal on both sides of the equation.

Front

What is the significance of isotopes in nuclear reactions?

Back

Isotopes are variants of elements with the same number of protons but different numbers of neutrons, affecting stability and decay processes.

Front

What is the role of helium in nuclear reactions?

Back

Helium is often produced as a byproduct of alpha decay, represented as 4_2He.

Front

What is the missing isotope in the equation 9_4Be + 1_1H → ? + 4_2He?

Back

The missing isotope is 6_3Li.
