Madam curie coined the term, and it is because of the activity a radio makes when near a radiation source
The term for a bond where an electron pair is shared but both electrons have been donated by one atom is called a coordinate covalent bond or a dative bond. In this type of bond, both electrons in the shared pair come from the same atom.
The term which means the amount that a given atom (or radical) attracts electrons is electronegativity.
The term that describes the defined space around an atom's nucleus where an electron is most likely to be found is called an "orbital." Orbitals are regions in an atom where the probability of finding an electron is highest, and they come in various shapes and sizes, such as s, p, d, and f orbitals. Each orbital can hold a maximum of two electrons with opposite spins.
Nuclear energy is the term for energy that comes from inside the nucleus of an atom. This energy can be released through processes such as nuclear fission or nuclear fusion.
For a substance the term is molecule, for an element the term is atom.

The term atom comes from ancient Greek meaning indivisible.
An atom smasher is an informal term for a particle accelerator.
When an atom has an electric charge it is called an ion.
