What is Element?
An element is a substance that cannot be broken down or decomposed into simpler substances by chemical means. In other words, an element is the most basic form of matter and it is composed of only one type of atom. It is the simplest form of matter and can be found on the periodic table. The periodic table is a chart that arranges all the elements known to man in order from lightest to heaviest based on their atomic mass. Each element has a unique set of properties that define it, such as its atomic number (the number of protons in its nucleus), its state (solid, liquid or gas at room temperature), and its reactivity with other elements. Elements are essential for life because they make up almost all matter in our universe, including living organisms. Most elements come from stars and supernovas, which create them through fusion reactions when hydrogen atoms join together to form heavier elements like carbon or oxygen. These elements are then distributed through space by asteroid impacts and meteorites before eventually forming planets like Earth where they become part of us. Atoms can also combine together in different ways to form molecules which make up many materials on Earth such as air, water and rocks; this process is called chemical bonding. By understanding how different kinds of atoms bond together we can create new materials that have specific properties this makes chemistry an incredibly important field that helps us understand our world better.
