Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen.
Element Hydrogen (H), Group 1, Atomic Number 1, s-block, Mass 1.008. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images.
Compounds of hydrogen are frequently called hydrides, even though the name hydride literally describes compounds that contain an H-ion. There is a regular trend in the formula of the hydrides across a row of the periodic table, as shown in the figure below.
3 ημέρες πριν · hydrogen (H), a colourless, odourless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The hydrogen atom has a nucleus consisting of a proton bearing one unit of positive electrical charge; an electron, bearing one unit of negative electrical charge, is also associated with this nucleus.
