    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...

    • Hydrogen (H): Most of the universe consists of hydrogen. It is a fuel and occurs in many compounds, such as water and hydrogen peroxide.
    • Helium (He): Helium is a monatomic gas. It is used in cryogenics, balloons, and as an inert atmosphere.
    • Lithium (Li): Lithium is a light, reactive metal. Uses include batteries, glass, ceramics, drugs, and lubricants.
    • Beryllium (Be): Beryllium is a lightweight metal used in aircraft and spacecraft components. It is an important alloying agent.

    2 days ago · In GCSE chemistry, an element is a substance made up from one type of atom. They cannot be broken down into anything simpler. Each element is represented by its own unique chemical symbol, which can be seen on the Periodic Table. All atoms of the same element will contain the same number of protons. For example, carbon atoms all have 6 protons.
