what is an element in chemistry A chemical element is any substance that cannot be decomposed into simpler substances by ordinary chemical processes Elements are the fundamental materials of which all matter is composed Learn more about the origins distribution and characteristics of chemical elements in this article

A chemical element is a chemical substance that cannot be broken down into other substances by chemical reactions The basic particle that constitutes a chemical element is the atom Chemical elements are identified by the number of protons in the nuclei of their atoms 1 known as the element s atomic number 2 In chemistry an element is defined as a pure substance composed of atoms that all have the same number of protons in the atomic nucleus In other words all atoms of an element have the same atomic number The atoms of an element sometimes called chemical element cannot be broken into smaller particles by any chemical means

An element is a substance whose atoms all have the same number of protons another way of saying this is that all atoms of a given element have the same number of protons Elements are the simplest chemical forms and thus can not be broken down through chemical reactions An element is a substance whose atoms all have the same number of protons another way of saying this is that all of a particular element s atoms have the same atomic number Elements are chemically the simplest substances and hence cannot be broken down using chemical reactions

A chemical element is a substance consisting of only one type of atom In other words all atoms in an element contain the same number of protons The identity of a chemical element cannot be changed by any chemical reaction However a nuclear reaction can transmute one element into another one An element is a substance that cannot be broken down into any other substance Every element is made up of its own type of atom This is why the chemical elements are all very different from

An element is a substance that cannot be broken down into simpler chemical substances There are about 90 naturally occurring elements known on Earth Using technology scientists have been able to create nearly 30 additional elements that do not occur in nature We can define an element as a type of matter that can not be broken down into a simpler substance by chemical means The only way to break down an element or change it into a different element is via a nuclear reaction
