the smallest particle of anelementthat has all the properties of the element. adj.,adjatom´ic.ƒThere are two main parts of an atom: thenucleusand theelectroncloud. The nucleus is made up ofprotons, which carry a positive electrical charge, and (except in hydrogen)neutrons, which contai...
the smallest component of an element having the chemical properties of the element, consisting of a nucleus containing combinations of neutrons and protons and one or more electrons bound to the nucleus by electrical attraction; the number of protons determines the identity of the element. ...
An atom is the basic unit of an element. When you see the chemical formula for water, H2O, it's telling you that each molecule of water is made up of two atoms of hydrogen and one atom of oxygen.In science class, you've probably come across atoms, the bits that make up molecules....
1. the smallest component of an element having the chemical properties of the element, consisting of a positively charged nucleus of neutrons and protons that exerts an electrical attraction on one or more electrons in motion around it. 2. this component as the source of nuclear energy. 3....
Definition of Atom What is an Atom? The atom is the smallest object that retains the properties of anelement. Atoms are composed ofelectronsand anucleus. The nucleus contains protons and neutrons. All atoms areelectrically neutral, because every atom has an equal number of electrons and protons...
An atom is the defining structure of anelement, which cannot be broken by any chemical means. Atypical atomconsists of a nucleus of positively-chargedprotonsand electrically neutralneutronswith negatively-chargedelectronsorbiting this nucleus. However, an atom can consist of a single proton (i.e.,...
