Write balanced nuclear equations for the following processes: $(\mathbf{a})$ rubidium-90 undergoes beta emission; $(\mathbf{b})$ selenium- 72 undergoes electron capture; $(\mathbf{c})$ krypton-76 undergoes positron emission; $(\mathbf{d})$ radium-226 emits alpha radiation.

Key Concepts

Alpha Decay

Alpha decay is characterized by the emission of an alpha particle (consisting of two protons and two neutrons), which reduces the atomic number of the original nucleus by two and the mass number by four. This process is essential in the transformation of heavy elements into lighter ones.

Positron Emission

Positron emission is a form of beta decay where a proton in the nucleus transforms into a neutron and emits a positron (the antimatter equivalent of an electron) along with a neutrino. This decay reduces the atomic number by one while leaving the mass number the same.

Radioactive Decay

Radioactive decay describes the process in which unstable atomic nuclei lose energy by emitting radiation in the form of particles or electromagnetic waves. This process leads to the transformation of elements and is governed by conservation laws, including the conservation of mass number and atomic number.

Beta Emission

Beta emission is a type of radioactive decay where a neutron is converted into a proton, releasing a beta particle (an electron) and an antineutrino. In nuclear equations, this process increases the atomic number by one while keeping the mass number constant.

Electron Capture

Electron capture is a decay process in which an inner orbital electron is absorbed by the nucleus, where it combines with a proton to form a neutron and emits a neutrino. This results in the atomic number decreasing by one while the mass number remains unchanged.
