Key Concepts

Atomic Number

Atomic number is the number of protons in the nucleus of an atom, which defines the element's identity. Any nuclear process that changes the number of protons will alter the atomic number, resulting in a different element.

Beta Decay

Beta decay is a nuclear process where a neutron is converted into a proton (or vice versa) with the emission of a beta particle. In beta minus decay specifically, a neutron decays into a proton and an electron, leading to a one-unit increase in the atomic number.

Nuclear Decay Processes

Nuclear decay processes include various mechanisms such as alpha decay, beta decay, electron capture, and gamma emission. Each process affects the nucleus differently, with specific implications for changes in atomic number and mass number.
