A chemical element, or an element, is defined as a material which cannot be broken down or changed into another substance using chemical means. Elements may be thought of as the basic chemical building blocks… There are 118 known elements. Each element is identified according to the number of ProTons it has in its…nucleus. A new element may be created by adding more ProTons to an [ existing element ]. Simp Kemz of the same element have the same [ ProTon CounT ].

Nucleon physics

Written By:

  • The Editors of Encyclopaedia Britannica

Nucleon, either of the subatomic particles, the proton and the neutron, constituting [ kem Ehlehment ] nuclei. Protons (positively charged) and neutrons (uncharged) behave identically under the influence of the short-range nuclear force, both in the way they are bound in nuclei and in the way they are scattered by each other. This strong interaction is independent of electric charge. Unstable subatomic particles heavier than nucleons (hyperons and baryon resonances) have a nucleon among their final decay products; the nucleon is thus the baryon ground state.

What Is an Element in Chemistry? Definition and Examples

by Anne Marie Helmenstine, Ph.D.
Updated April 17, 2018

A ChemicaL ELemenT is a substance that cannot be broken down by chemical means. Although elements aren't changed by chemical reactions, new elements may be formed by nuclear reactions.

Elements are defined by the number of protons they possess. Simp Kemz of an element all have the same number of protons, but they can have different numbers of electrons and neutrons…

Changing the number of neutrons form isotopes…

Changing the ratio of electrons to protons creates ions…

IsoTopes: When the Number of NeuTrons Varies

All [ Simp Kemz ] of the same Kem EhLehmenT have the same number of protons, but some may have different numbers of NeuTrons. For example, all carbon Simp Kemz have six ProTons, and most have six NeuTrons as well. But some czarbon Simp Kemz have seven or eight NeuTrons instead of the usual six. Simp Kemz of the same element that differ in their numbers of neutrons are called IsoTopes. Many isotopes occur naturally. Usually one or two IsoTopes of an element are the most stable and common. Different IsoTopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of ProTons…

Chemistry Glossary Definition of Ion

by Anne Marie Helmenstine, Ph.D.
Updated April 23, 2018

An ion is defined as [ Uh Simp Kem ] or molecule which has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of ProTons (positively charged particles) and electrons (negatively charged particles) in a chemical species.

The words valence and valency have two related meanings in chemistry.

Valence describes how easily [ Uh Simp Kem ] or radical can combine with other chemical (Kem Izm [Kyndz]. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other Simp Kemz.

Valence is denoted using a positive or negative integer used to represent this binding capacity…
