element

An element is a substance that cannot be broken down into any other substances. It is made up of tiny particles called atoms, and each element has its own unique type of atom. For example, the element gold is made up of gold atoms, and the element oxygen is made up of oxygen atoms.

Elements are the building blocks of everything in the world around us. They are found in the air we breathe, the food we eat, and the things we use every day. There are over 100 elements, and they are all different from each other. Some elements are metals, like gold and silver. Others are non-metals, like oxygen and hydrogen.

Elements are important because they can be combined to form new substances called compounds. For example, water is a compound that is made up of hydrogen and oxygen atoms. Compounds can have very different properties from the elements that they are made up of. For example, water is a liquid, but hydrogen and oxygen are gases.

The element oxygen is essential for life.
