Hydrogen
Designed by simbamerch
Hydrogen is a chemical element with chemical symbol H and atomic number 1. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Non-remnant stars are mainly composed of hydrogen in the plasma state. The most common isotope of hydrogen, termed protium (name rarely used, symbol 1H), has one proton and no neutrons. The universal emergence of atomic hydrogen first occurred during the recombination epoch. At standard temperature and pressure, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with the molecular formula H2. Since hydrogen readily forms covalent compounds with most nonmetallic elements, most of the hydrogen on Earth exists in molecular forms such as water or organic compounds. Hydrogen plays a particularly important role in acid–base reactions because most acid-base reactions involve the exchange of protons between soluble molecules. In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) when it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The hydrogen cation is written as though composed of a bare proton, but in reality, hydrogen cations in ionic compounds are always more complex. As the only neutral atom for which the Schrödinger equation can be solved analytically, study of the energetics and bonding of the hydrogen atom has played a key role in the development of quantum mechanics. Hydrogen gas was first artificially produced in the early 16th century by the reaction of acids on metals. In 1766–81, Henry Cavendish was the first to recognize that hydrogen gas was a discrete substance, and that it produces water when burned, the property for which it was later named: in Greek, hydrogen means "water-former". Industrial production is mainly from steam reforming natural gas, and less often from more energy-intensive methods such as the electrolysis of water. Most hydrogen is used near the site of its production, the two largest uses being fossil fuel processing (e.g., hydrocracking) and ammonia production, mostly for the fertilizer market. Hydrogen is a concern in metallurgy as it can embrittle many metals, complicating the design of pipelines and storage tanks. . . . . . red bubble t shirts, t shirts art design, redbubble design, shirt artist, artistic tees, make a tshirt design, cool t shirt art, shirt graphics, custom t shirts near me, redbubble shirts, cool t shirt designs, artistic tee, best online tshirt store, artwork tees, t shirt design art, artsy tees, awesome t shirt designs, buy printed t shirts online, order t shirts online, custom printed t shirts online, pixelated t shirt, t shirts art design, pixel art shirt, vintage t shirts, cool t shirts, pixel shirts, t shirts for sale, shirt online shop, funny tees online, best online tshirt store, buy online t shirts, tee shirt shop, online t shirt shop, t shirt selling, custom printed t shirts, t shirt design and sell, printed t shirts online shopping, best online tshirt store, cheap online t shirts, cool printed t shirts online, buy mens t shirts, unique tee shirts online, buy best t shirts online, shirt shop online, buy mens t shirts online

love the shirts

by Karen B. on Jun 20, 2018

I'm know around the office for my t-shirts ...they have to say something; whether it be historical figures, musicians or a political statement. Your shirts have a good fit and they wash and wear well. I've spent big bucks on T-shirts that aren't nearly as durable as the quality shirts you offer. Thanks for putting out a quality product
