Atom

The smallest part of an element that retains its properties. It is possible to 'split' the atom up further into components; protons - which have a positive charge, electrons, which have a negative charge and neutrons which have no charge. The simplest atom is hydrogen, which consists of a single proton nucleus and has a single electron forming an orbit or shell around the proton. The next simplest is helium, with two protons and two neutrons in the nucleus with two electrons orbiting within the shell - see selow for diagram: ...

atom

(Learning Modules / Chemistry / Polymers) The simplest unit which defines a particular element. Atoms are made up of protons, an equal number of electrons, and neutrons. Different atoms differ in their number of protons and electrons.

Atom

The smallest unit capable of combining with another, an atom is a particle capable of combining with another.

[time] The atom was a unit of time referred to in medieval philosophical writings as the smallest possible division of time. The earliest known occurrence in English is in Byrhtferth`s Enchiridion (a science text) of 1010–1012, where it was defined as 1/564 of a momentum (1½ minutes), and thus equal to 15/94 of a second. It was used in t...

Atom

The basic structure of which all matter is made. It is made up of three particles; protons and neutrons (which make up the nucleus) and electrons (which orbit the nucleus). (The one exception to this is hydrogen which has only a proton at its nucleus. In its basic state an atom will form an element, the kind of element being dictated by the structu...

Atom

A particle of matter which cannot be broken up by chemical means. Atoms have a nucleus consisting of positively-charged protons and uncharged neutrons of the same mass. The positive charges on the protons are balanced by a number of negatively-charged electrons in motion around the nucleus
