What is an element in chemistry BBC Bitesize?
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 each other.
What is the definition of an element GCSE?
• An element is a substance that consists of only one type of atom and it cannot be broken. down into anything simpler by chemical means.
What is an element simple definition?
Chemical element, also called element, any substance that cannot be decomposed into simpler substances by ordinary chemical processes. Elements are the fundamental materials of which all matter is composed.
What is an element for kids?
Science >> Chemistry for Kids. An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium. Atomic Number.
What is the difference between elements and compounds and mixtures?
Element: Pure substance consisting of one type of atom. Compound: Pure substance consisting of two or more different atoms. Mixture: Two or more different substances not chemically combined. Homogeneous mixture: A mixture with a uniform composition.
What’s the difference between atoms elements and compounds?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What’s the difference between an element and a compound?
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.
What are types of elements?
The three types of elements are metals, non- metals and metalloids.
What are the four basic elements?

What are element examples?
Elements are substances that are made from one type of atom. An element cannot be broken down into any other substance. There are 92 naturally occurring elements and everything in the universe is made from these basic building blocks. Common examples include carbon, sulfur, oxygen, iron, copper, aluminium.
How many different elements are there in KS3?
KS3 Atoms, elements and compounds There are over 100 different elements, which are made up of atoms. Elements can be divided into metals and non-metals.
Which is the best description of an element?
Most are metals, a few are metalloids (also known as semi-metals), and the rest are non-metals. A pure substance made from more than one type of element chemically bonded together. Elements bond in fixed ratios and so can be represented by a chemical formula.
What makes an element different from other elements?
The atoms in a particular element are the same as each other, and they are different from the atoms of all other elements. For example, lead and gold are elements. A piece of pure gold contains only gold atoms. A piece of pure lead contains only lead atoms.
