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...
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....
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.
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.,...
The meaning of ATOM is the smallest particle of an element that can exist either alone or in combination. How to use atom in a sentence. Did you know?
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. ...
Atomic number refers to the number of protons present in the nucleus of the smallest unit of matter. It is the identity of an atom. For instance, the atomic number of carbon is six, which implies that the carbon atom has six protons inside its nucleus. An element can be defined as a ...
atomic number- the order of an element in Mendeleyev's table of the elements; equal to the number of protons in the nucleus or electrons in the neutral state of an atom of an element number- a concept of quantity involving zero and units; "every number has a unique position in the sequ...
Atomsare the foundation of matter, which is everything that makes up the universe around us. Each kind of atom makes up a pure substance called an element. You may have heard of oxygen, lead, and gold. Well, these are all examples of elements. Can you believe that a pure gold ...
