Hydrogen

What do we mean by hydrogen?

A colorless, highly flammable element, that occurs as a diatomic molecule, H2, the lightest of all gases and the most abundant element in the universe, used in the production of synthetic ammonia and methanol, in petroleum refining, in the hydrogenation of organic materials, as a reducing atmosphere, in oxyhydrogen torches, in cryogenic research, and in rocket fuels. Atomic number 1; atomic weight 1.00794; melting point −259.1°C; boiling point −252.8°C; density at 0°C 0.08988 gram per liter; valence 1. cross-reference: Periodic Table. noun

Hydrogen compounds with strongly electronegative elements or radicals, easily exchanging hydrogen for strongly electropositive elements or radicals to form salts, are the same as acids: as hydrogen chlorid (hydrochloric acid), hydrogen sulphate (sulphuric acid), etc. noun

Chemical symbol, H. One of the elementary substances, existing as a colorless, tasteless, and inodorous gas. noun

H2S, a colorless inflammable gas having a sweetish taste and an exceedingly fetid smell resembling rotten eggs. It is extremely poisonous when inhaled. It has feeble acid properties, and its compounds with bases are called sulphids. It occurs in the emanations of volcanoes, and is evolved when animal or vegetable tissue containing sulphur decays. It also occurs in mineral springs, being liberated by the reduction of gypsum or other sulphates through the action of a microbe. noun

A gaseous element, colorless, tasteless, and odorless, the lightest known substance, being fourteen and a half times lighter than air (hence its use in filling balloons), and over eleven thousand times lighter than water. It is very abundant, being an ingredient of water and of many other substances, especially those of animal or vegetable origin. It may by produced in many ways, but is chiefly obtained by the action of acids (as sulphuric) on metals, as zinc, iron, etc. It is very inflammable, and is an ingredient of coal gas and water gas. It is standard of chemical equivalents or combining weights, and also of valence, being the typical monad. Symbol H. Atomic weight 1. noun

An old name for ethylene. noun

See under Carbureted. noun

A thick, colorless liquid, H2O2, resembling water, but having a bitter, sour taste, produced by the action of acids on barium peroxide. It decomposes into water and oxygen, and is manufactured in large quantities for an oxidizing and bleaching agent. Called also oxygenated water. noun

A chemical name for water, H�O. noun

A colorless inflammable gas, H2S, having the characteristic odor of bad eggs, and found in many mineral springs. It is produced by the action of acids on metallic sulphides, and is an important chemical reagent. Called also sulphureted hydrogen. noun

The lightest chemical element (symbol H) with an atomic number of 1 and atomic weight of 1.00794. noun

Molecular hydrogen (H2), a colourless, odourless and flammable gas at room temperature. noun

An atom of the element. noun

A sample of the element. noun

A nonmetallic univalent element that is normally a colorless and odorless highly flammable diatomic gas; the simplest and lightest and most abundant element in the universe noun

The lightest chemical element (symbol H), with an atomic number of 1 and atomic weight of 1.00794.

Molecular hydrogen (H2), a colourless, odourless and flammable gas at room temperature.

An atom of the element.

A sample of the element.

Hydrogen is a twatty element. it only has one proton. i mean, what the fuck is up with that? and then it goes and annoys the other elements by latching on to them all the time. Urban Dictionary

A term for being a slut, since the element of Hydrogen can bond with every element. Urban Dictionary

The first element on the periodic table. Burns with glee when lit, and explodes when lit near oxygen. Urban Dictionary

The reason that the Hindenberg was a bad idea. Urban Dictionary

An elemental gas with a unique property that, if given enough time, will think about itself. Urban Dictionary

Better than ptm at tfc :D Urban Dictionary

A substance or an entity primarily or partially composed of hydrogen atoms. Urban Dictionary

The first element, with only 1 proton and 1 electron, that loves to bond with every element it can. It is also highly flammable. Urban Dictionary

A suggestion considered when sober. This suggestion is often used when one is sober and thinks to what his/hers high self would do. Adapted from the word ¨High suggestion ¨ which said repeatedly can emulate the word ¨Hydrogen¨. Urban Dictionary

Element number one, is in the group other non-metals (alongside C, N, O, P, S, Se), has an atomic weight of 1.00974 amu, a hexagonal crystal structure, and a atomic radius of 53 picometers (pm). It is found the Sun, and was once used in blimps, before helium as used. Urban Dictionary
