aatomituumad
Aatomituumad, also known as atomic units, are a system of natural units which are used as a system of measurement in atomic physics and theoretical chemistry. This system is based on the atomic properties of electrons and protons, and it is designed to simplify calculations in these fields by normalizing certain physical constants to 1. The primary atomic units include the atomic unit of charge, the atomic unit of mass, and the atomic unit of length, among others.
The atomic unit of charge, often denoted as 'e', is the elementary charge of an electron, approximately
These units are particularly useful in quantum mechanics and other areas of physics and chemistry where atomic
