What is the best way to describe hydrogen?
a colorless, odorless, flammable gas that combines chemically with oxygen to form water: the lightest of the known elements.
What are 3 characteristics of hydrogen?
Hydrogen is a colorless, odorless, tasteless, and nonpoisonous gas under normal conditions on Earth. It typically exists as a diatomic molecule, meaning each molecule has two atoms of hydrogen; this is why pure hydrogen is commonly expressed as “H2“.
What exactly is hydrogen?
Hydrogen is a chemical element. It has the symbol H and atomic number 1. It has a standard atomic weight of 1.008, meaning it is the lightest element in the periodic table. Hydrogen is the most common chemical element in the Universe, making up 75% of all normal (baryonic) matter (by mass).
Who described hydrogen?
Hydrogen was discovered by the English physicist Henry Cavendish in 1766. 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.
How do you explain hydrogen to a child?
Hydrogen is the very first element on the periodic table, and it is the most common element in the universe, making up about 75% of its mass. Hydrogen is extremely flammable, meaning it catches fire easily. What is this? It is a colorless, odorless, and tasteless gas.
Is hydrogen gas H2 or H?
Hydrogen has a molar mass of 1 and it's molecular formula is H2. Hydrogen, H, is the lightest element with the atomic number 1. It is a colorless, odorless, tasteless, and highly flammable gas with the molecular formula H2.
What are 4 physical descriptions of hydrogen?
At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2.
What are the properties and uses of hydrogen?
Hydrogen also has many other uses. In the chemical industry it is used to make ammonia for agricultural fertiliser (the Haber process) and cyclohexane and methanol, which are intermediates in the production of plastics and pharmaceuticals. It is also used to remove sulfur from fuels during the oil-refining process.
Which is the best definition of hydrogen bonding?
The definition of hydrogen bond is a chemical bond between the hydrogen atom and an electronegative atom. ... A chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom, especially a nitrogen, oxygen, or fluorine atom, usually of another molecule.
Is hydrogen a water?
What Is Hydrogen Water? Hydrogen water is simply pure water with extra hydrogen molecules added to it. Hydrogen is a colorless, odorless, non-toxic gas that binds to other elements like oxygen, nitrogen, and carbon to form various compounds, including table sugar and water ( 1 ).
What kind of mixture is hydrogen?
In 1929 Karl Friedrich Bonhoeffer, a German physical chemist, and Paul Harteck, an Austrian chemist, on the basis of earlier theoretical work, showed that ordinary hydrogen is a mixture of two kinds of molecules, ortho-hydrogen and para-hydrogen.
