Hydrogen 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 H 2.xidation of hydrogen removes its electron and gives H+ , which contains no electrons and a nucleus which is usually composed of one proton. That is why H+ is often called a proton. This species is central to discussion of acids.

- · just now. Report Abuse. Hydrogen is a gas, so it's neither shiny or dull. Hydrogen is also very explosive, so it conducting electricity isn't a good idea! (So, no...) I'm guessing the 298K is 298 Kelvin, a temperature measure, but I have no idea what it's related to. Joe B. · 8 years ago. Thumbs up.

Hydrogen The hydrogen atom is composed of a very light, negatively charged electron, and a heavy, positively charged proton. The weight of the proton is 1.00758 atomic mass units (about 6.02 x 10 23 protons weigh 1.00758 grams). The electron weighs about 1/1837 of the proton's weight.The diameter of a proton has a fairly definite meaning, and is 1.6 x 10 -13 cm. The diameter of a hydrogen atom in its ground state is around 1 x 10 -8 cm, so the ratio of the diameters is about 1.6 x 10 -5, which makes the ratio of the volumes 4.1 x 10 -15.he diameter of a proton has a fairly definite meaning, and is 1.6 x 10 -13 cm.

Yellow This article is about the color. For other uses, see Yellow (disambiguation). Yellow is the color between green and orange in the spectrum of visible light, the color of ripe lemons, sunflowers and gold. It is a primary color in subtractive color, used in color printing. According to surveys in Europe, Canada and the United States, yellow is the color people most often associate with amusement, gentleness, and spontaneity, but also with duplicity, envy, jealousy, avarice, and, in the U.S., with cowardice.

Silane 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.

Colour test that can show hidden health problems: Shade of your urine can reveal everything from cancer to kidney trouble TANITH CAREY talked to the experts to find out what the colour of your urine really means. Urine is usually pale yellow-the colour comes from urochrome, a yellow pigment that's a by-product when bile, a greenish-coloured liquid, is broken down. Bile is produced by the liver and helps us digest fats. It also removes what is left over when red blood cells are broken down.

Space Terms Hydrogen is the simplest element of all, and the lightest. It is also by far the most common element in the Universe. Over 90 percent of the atoms in the Universe are hydrogen. In its commonest form, the hydrogen atom is made of one proton, one electron, and no neutrons. Hydrogen is the only element that can exist without neutrons. Hydrogen is a colorless, odorless gas which exists, at standard temperature and pressure, as diatomic molecules, H2.

Neon lighting The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals are used to produce other colors, such as hydrogen (red), helium (yellow), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or pictures.

Why does hydrogen gas only emit light of certain colors when electric current is passed through it? Hydrogen gas only emits certain wavelengths of light because the energy levels of hydrogen atoms are quantized. Without getting too deep into it, this means that the hydrogen atoms can only be in certain discrete energy states (they can only have certain amounts internal energy). When electric current is passed through hydrogen, it jumps the energy levels of the atoms up a level or two, and then the atom goes back.

Hydrogen and Oxygen However, hydrogen and oxygen have some common properties. They are both colorless, odorless gases, and they both readily react with other elements—making them  reactive elements. But in many ways they are very different from each other. Hydrogen has the lowest density of all the elements.

It's Elemental Hydrogen is pronounced as HI-dreh-jen. History and Uses: Scientists had been producing hydrogen for years before it was recognized as an element. Written records indicate that Robert Boyle produced hydrogen gas as early as 1671 while experimenting with iron and acids. Hydrogen was first recognized as a distinct element by Henry Cavendish in 1766. Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen.

What are the flame colors for hydrogen and oxygen? A high carbon / hydrogen + oxygen samples will burn with a sooty luminous flame. both luminosity and soot are a result of free (unburnt carbon) As the carbon in the sample decreases relative to hydrogen and/or oxygen soot and luminosity decreases Oxygen content should have a more pronounced effect than hydrogen at reducing soot and luminosity.
