Atom Definition Chemistry The smallest particle of an element, which may or may not have an independent existence but always takes place in a chemical reaction is called an atom. An atom is defined as the smallest unit that retains the properties of an element. An atom is composed of sub-...

The Theory of Atoms in Molecules (AIM) developed by Bader is a wonderful extension of quantum mechanics to chemistry. It gives a quantum definition for atoms (open systems) in molecules, showing that they are bounded by zero-flux surfaces in the gradient vector field of the electron density....

If one really can't avoid using an atomic radius, then he should check exactly what definition is used for the data he finds. "Covalent" radius isn't accurate enough. 20% discrepancy is common.This goes worse with hydrogen, whose single shell changes much its extension depending on the ...
We're just been learning about emission and absorption spectra and how these relate to the energy levels of electrons in an atom but its brought up 2 questions. 1. In chemistry our notes say that the energy change between levels gets smaller as you move out from the nucleus, however in ...
What is an atom called in nuclear chemistry? Which is a substance that is made up of only one type of atom? What happens when oxygen atoms share electrons? Which subatomic particles are involved in chemical bonding? Why do atoms react with other atoms?
