Alpha, Beta and Gamma Radiation: Balancing Nuclear Reactions

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which an unstable nucleus transforms a neutron into a proton and emits a beta particle (an electron or positron).

Front

What is radioactive decay?

Back

Radioactive decay is the disintegration of an unstable nucleus into one or more different elements or isotopes, accompanied by the emission of radiation.

Front

What is an isotope?

Back

An isotope is an atom of an element that has the same number of protons but a different number of neutrons.

Front

Why does alpha decay occur?

Back

Alpha decay occurs because the nucleus is too large to be stable, leading to the emission of an alpha particle (2 protons and 2 neutrons).

Front

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

Back

The missing isotope is 6_3Li.

Front

What is the role of neutrons in an atom?

Back

Neutrons help stabilize the nucleus by offsetting the repulsive forces between protons.

Front

What is the difference between alpha, beta, and gamma radiation?

Back

Alpha radiation consists of helium nuclei, beta radiation consists of electrons or positrons, and gamma radiation consists of high-energy photons.

Front

What happens during beta decay?

Back

During beta decay, a neutron in the nucleus is converted into a proton, increasing the atomic number by one and emitting a beta particle.

Front

What is the significance of the proton-to-neutron ratio?

Back

The proton-to-neutron ratio is crucial for nuclear stability; an imbalance can lead to radioactive decay.

Front

What is a nuclear equation?

Back

A nuclear equation represents a nuclear reaction, showing the initial and final nuclei and any emitted particles.
