A.

What is so unique about hydrogen?

Special Properties of Hydrogen. Hydrogen is an element that forms a diatomic molecule. Diatomic molecules are composed of two atoms of the same element and generally exist because the element is so reactive that it needs to bond to another atom. The reactivity of hydrogen contributes to many of its unique properties.

  • How does it work hydrogen?

    While the hydrogen gas is very flammable, it is not burned. Instead, the gas is passed through a fuel cell stack that mixes the pure hydrogen with atmospheric oxygen to generate electric current. The electricity is then used to power one or more electric motors driving the wheels.
  • What are the characteristics and uses 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. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.
B.

What are the main 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.
  • How do we use hydrogen?

    It is the lightest element and can be used as a lifting agent in balloons. Since Hydrogen gas is highly flammable, it can be dangerous to use. But this property and others make Hydrogen suitable for use as a fuel. The most common use of Hydrogen is in chemical processes and reactions.
  • What is made up of hydrogen?

    Hydrogen is found in large amounts in giant gas planets and stars, it plays a key role in powering stars through fusion reactions. Hydrogen is one of two important elements found in water (H2O). Each molecule of water is made up of two hydrogen atoms bonded to one oxygen atom.
  • Is hydrogen used in rocket fuel?

    Liquid hydrogen delivers a specific impulse about 30%-40% higher than most other rocket fuels. Liquid oxygen and liquid hydrogen are used as the propellant in the high efficiency main engines of the Space Shuttle.
C.

What is the chemical family of hydrogen?

Nonmetal
Alkali metal
Period 1 element
  • Is oxygen a chemical?

    Chemical Properties of Oxygen. At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element.
  • What are the names of the various chemical families?

    The following collective names are recommended by IUPAC:
    • Alkali metals – The metals of group 1: Li, Na, K, Rb, Cs, Fr.
    • Alkaline earth metals – The metals of group 2: Be, Mg, Ca, Sr, Ba, Ra.
    • Pnictogens – The elements of group 15: N, P, As, Sb, Bi.
    • Chalcogens – The elements of group 16: O, S, Se, Te, Po.
  • What is the usual atomic structure of hydrogen?

    A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.
