Definition of hydrogen in English:

hydrogen

noun ˈhʌɪdrədʒ(ə)nˈhaɪdrədʒən

mass noun

A colourless, odourless, highly flammable gas, the chemical element of atomic number 1.
（化学元素）氢（符号：H ）
Hydrogen is the lightest of the chemical elements and has the simplest atomic structure, a single electron orbiting a nucleus consisting of a single proton. It is by far the commonest element in the universe, although not on the earth, where it occurs chiefly combined with oxygen as water
Example sentencesExamples
- Chemically, oil is made up of chains of carbon, hydrogen and oxygen called fatty acid.
- Indeed it's thought that after the big bang the only elements around were hydrogen and helium.
- We know that for a fact because we've measured the isotope ratio of deuterium and hydrogen.
- Yes we can say that water is made up of two atoms of hydrogen and one of oxygen but how are these atoms combined to make this substance we call water?
- Food waste is turned into hydrogen, methane and carbon monoxide by the heat of the exhaust.
- In the water molecule there are three atoms: two of hydrogen and one of oxygen.
- For example, the formula of hydrochloric acid is HCl - one atom of hydrogen and one of chlorine.
- As the explosive mixture of hydrogen and oxygen ignited, the two turbopumps spun up to speed.
- He believes his firm will be in full commercial production turning silicon to hydrogen to be used to power cars.
- It was a very dry world, almost no water, and not much carbon, hydrogen or oxygen either.
- Energy is generated by the reaction of hydrogen and oxygen across a catalytic membrane.
- A fuel cell combines hydrogen and oxygen into water and in the process creates electricity that is used to power the car.
- Once a star has burnt most of its hydrogen to helium, it starts to cool.
- The fuel cell combines hydrogen with oxygen from the air to generate electricity that powers the vehicle.
- The elements of which water is composed, hydrogen and oxygen, both have stable isotopes.
- Try substituting fluorine for hydrogen in some compounds and the consequences can be dramatic.
- Pour in the water and watch it separate into hydrogen and oxygen, forming a gas to power your vehicle across the floor.
- The water could be used for drinking and also split into hydrogen and oxygen to make fuel for future trips.
- We know that the Moon is low on certain chemicals such as hydrogen and carbon.
- In composition it resembles a small star, with helium and hydrogen as the main gases.

Derivatives

hydrogenous

adjective hʌɪˈdrɒdʒɪnəshaɪˈdrɑdʒ(ə)nəs

Based on new results, the role played by hydrogenous species in the generation is explored.
Example sentencesExamples
- The small structural differences suggest different relative stabilities for the hydrogenous and deuterated salts, which may be sufficient to stabilize the hydrogenous salt in the anomalous structural form.
- In the U.S., we import almost everything under the sun, and many of those imports are hydrogenous.
- Both instruments sense the presence of hydrogenous materials by measuring variations in the thermal and epithermal neutron fluxes.
- These materials are made of a low density solid hydrogenous material which binds a powder of medium density materials.

Origin

Late 18th century: coined in French from Greek hudro- 'water' + -genēs (see -gen).
