Ionic
An element is REDUCED. By that, it means that an element of a compound or an element in itself has gained electron/s when the reaction occurs. You can find this out when you see a change in their oxidation number.
A chlorine atom needs one additional electron in order to become stable.
Some elements achieve stable electron configurations through the transfer of electrons, which occurs in ionic bonding. This process involves one element losing electrons (cation) and another element gaining electrons (anion) to reach a stable configuration. Ionic bonding typically occurs between metals and nonmetals with significant differences in electronegativity.

An oxidation number of -1 means that the element has gained one electron, indicating that it is in its reduced state (has undergone reduction). This often occurs when an element gains an electron to achieve a stable electron configuration.
Hydrogen is the simplest, lightest element. It normally occurs as "protium", the atom having one proton and one electron.
When a radioactive element slowly turns into another element/s when it emits various particles.
Ionic bonds form when one element transfers electrons to another element. This occurs when an element with a high electron affinity (EA) transfers electrons to an element with a low ionization energy (IE). The transfer of electrons creates ions that are held together by electrostatic forces, forming an ionic bond.
Lots of wrong answers out there, tested this on school, the answer is: Drops from a higher to a lower energy level
Ions are formed in the environment by the transfer of electrons. This occurs in the atom when one electron transfers to another.
If the parent element undergoes beta decay, it will transform into a daughter element with an atomic number that is one greater than the parent element. This occurs when a neutron in the nucleus is transformed into a proton, releasing an electron (beta particle) and an antineutrino.
