An atom is the smallest unit of ordinary matter that retains the chemical properties of an element. Atoms are the fundamental building blocks of matter, forming molecules, compounds, living organisms, planets, and stars. Every solid, liquid, gas, and plasmaâexcluding exotic states such as neutron starsâis composed of atoms. The modern atomic concept emerged gradually, from […]
Oxygen is the chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group in the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements as well as with other compounds. Oxygen is Earth’s most abundant element, and after hydrogen and helium, it is the third-most abundant element in the universe.
Zinc is a chemical element with the atomic number 30 and the symbol Zn. At room temperature, zinc is a somewhat brittle metal with a silvery-greyish look when oxidation is eliminated. It is the first element in periodic table group 12 (IIB). Zinc is chemically similar to magnesium in various ways: both metals have just
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a lightweight, silvery-white alkaline earth metal and one of the most abundant elements in the Earthâs crust and oceans. Magnesium plays a crucial role in biological systems, industrial manufacturing, metallurgy, and chemical processes. As a member of Group 2 in
Hydrogen is a chemical element with the symbol H and atomic number 1, making it the lightest and most abundant element in the universe. It consists of a single proton and a single electron in its most common isotope, protium. Hydrogen plays a central role in cosmology, stellar physics, chemistry, energy systems, and biological processes.
A list of chemical elements is an organized catalog of the known fundamental substances that consist of atoms defined by a specific number of protons in their nuclei. Each element represents a distinct form of matter and is arranged within the periodic table according to atomic number, electron structure, and recurring chemical properties. As of
