Any of the 118 elements on the periodic tableis an example of any element. Because elements are defined by the number of protons, any isotopes, ions, or molecules consisting of one type of atom are also examples of elements. But, if you are asked to name examples of elements, play it safe and list any of the elements on the periodic table rather th...
If a substance contains more than one type of atom, it’s not an element. Fictional elements aren’t real chemical elements. Examples of substances that aren’t elements include: 1. Water (H2O, composed of hydrogen and oxygen atoms) 2. Steel (composed of iron, nickel, and other elements) 3. Brass (composed of copper, zinc, and sometimes other elements...
There are three ways to refer to individual elements. Each element has a name, an element symbol, and an atomic number. The International Union of Pure and Applied Chemistry (IUPAC) approves standard names and symbols, but within an individual country, other element names might be used. Some element names are historical, but most were named by the ...
An element consists of only one type of atom. A molecule is composed of two or more atoms joined together by chemical bonds. Some molecules are examples of elements, such as H2, N2, and O3. A compound is a type of molecule consisting of two or more differentatoms joined by chemical bonds. All compounds are molecules, but not all molecules are compo...

Dec 5, 2019 · 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.
