The Handy Element Hydrogen | Periodic Table - ChemTalk
Learn all about the element hydrogen of the perodic table, along with its properties and fun facts. It's the smallest element, but it has a big role in chemistry.
chemistrytalk.orgHydrogen is the simplest atom, featuring one proton and one electron derives its name from the Greek word for water maker, reflecting its reaction with oxygen to form water. It has atomic number 1, and its atomic weight is about 1.008. Electrons are held by electromagnetic attraction and is described by quantum mechanics rather than a fixed orbit. Its structure and roles span chemistry and astrophysics in many summaries. As the simplest and most abundant element, hydrogen dominates many landscapes of science. Hydrogen appears as a colorless, odorless gas with flammable properties.
