Hydrogen is the only element that forms compounds in which the valence electrons are in the n = 1 shell as a result, hydrogen can have three oxidation states, . The element hydrogen - known isotopes isotopes of the element hydrogen [click for main data]most of the isotope data on this site has been obtained from the national nuclear data center. Hydrogen concept first element on the periodic table , hydrogen is truly in a class by itself it does not belong to any family of elements, and though it is a nonmetal, it appears on the left side of the periodic table  with the metals. Hydrogen is the first element in the periodic table it is the simplest possible atom composed of one proton in the nucleus which is orbited by a single electron hydrogen is the lightest of the elements and is the most abundant element in the universe.
Photographs and descriptions of many samples of the element hydrogen in the periodic table. Hydrogen - reactivity of hydrogen: one molecule of hydrogen dissociates into two atoms (h2 → 2h) when an energy equal to or greater than the dissociation energy (ie, the amount of energy required to break the bond that holds together the atoms in the molecule) is supplied. For nearly 100 years, scientists have dreamed of turning the lightest of all the elements, hydrogen, into a metal now, in a stunning act of modern-day alchemy, scientists at harvard university . Hydrogen is the only element whose isotopes have been given different names deuterium and tritium are both used as fuel in nuclear fusion reactors one atom of deuterium is found in about 6000 ordinary hydrogen atoms.
Hydrogen (h), with an atomic number of 1, is a colorless gas that wasn’t formally discovered as an element by henry cavendish until 1766, but it was accidentally found nearly one hundred years before by robert boyle it is a nontoxic, odorless, colorless gas that naturally exists in our universe . The element hydrogen hydrogen (latin: hydrogenium) is the chemical element in the periodic table that has the symbol h and atomic number 1 at standard temperature . Element reactions the following uses for hydrogen are gathered from a number of sources as well as from anecdotal comments i would be delighted to receive corrections as well as additional referenced uses.
Hydrogen first element in the periodic table in normal conditions it’s a colourless, odourless and insipid gas, formed by diatomic molecules, h 2the hydrogen atom, symbol h, is formed by a nucleus with one unit of positive charge and one electron. Hydrogen definition is - a nonmetallic element that is the simplest and lightest of the elements, is normally a colorless odorless highly flammable diatomic gas, and is used especially in synthesis a nonmetallic element that is the simplest and lightest of the elements, is normally a colorless odorless highly flammable diatomic gas, and is. Hydrogen is a chemical element with symbol h and atomic number 1 with a standard atomic weight of 1008, hydrogen is the lightest element on the periodic tableits monatomic form (h) is the most abundant chemical substance in the universe, constituting roughly 75% of all baryonic mass.

Comprehensive information for the element hydrogen - h is provided by this page including scores of properties, element names in many languages, most known nuclides and technical terms are linked to their definitions. Hydrogen is the absolute smallest of all elements, so small that four billion, laid end to end, could fit on the head of one pin at room temperature hydrogen is a clear gas hydrogen gas (h 2) is a molecule made of two hydrogen atoms bonded together it has no taste or odor and is not toxic it . The element hydrogen was created in the big bang well not exactly the astro physicists would give some precise time after the plasma created in the big bang cools down a bit and then hydrogen atoms begin forming.
