What is the simple definition of hydrogen?
Definition of hydrogen : a nonmetallic gaseous chemical element with atomic number 1 that is the simplest and lightest of the elements and that is used especially in the processing of fossil fuels and the synthesis of ammonia — see Chemical Elements Table — compare deuterium, tritium.
What is the true meaning of power?
1 : possession of control, authority, or influence over others. 2 : a nation that has influence among other nations a foreign power. 3 : the ability to act or produce an effect It’s in your power to change things. 4 : the right to do something the president’s powers.
Who discovered power of 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.
What are the main uses of hydrogen?
Hydrogen is used in many industrial processes.

What are 3 interesting facts about hydrogen?
Hydrogen Facts
- Hydrogen is the most abundant element.
- There are three natural isotopes of hydrogen: protium, deuterium, and tritium.
- Hydrogen gas is extremely flammable.
- Hydrogen compounds commonly are called hydrides.
- Hydrogen may be produced by reacting metals with acids (e.g., zinc with hydrochloric acid).

- Hydrogen is the most abundant element on earth. Hydrogen is an alternative fuel that has very high energy content by weight.
- Fuel cells can be used to power several applications.
- Fuel cells are a clean way to produce power.
- Fuel cell cars are very similar to traditional gasoline powered cars.
Why is it called hydrogen?
The earliest known important chemical property of hydrogen is that it burns with oxygen to form water, H2O; indeed, the name hydrogen is derived from Greek words meaning “maker of water.”
What is hydrogen power and how does it work?
The hydrogen travels through the anode of a fuel cell and oxygen goes through the cathode. At the anode, the hydrogen is split into electrons and protons. The protons move through the electrolyte membrane, while the electrons travel through a circuit, generating an electric current and excess heat.
Why is hydrogen important to life?
Hydrogen is essential to our life – it fuels the sun, which converts hundreds of million tons of hydrogen into helium every second. And two hydrogen atoms are attached to one oxygen atom to make water. Both these things make our planet habitable.
What are some bad things about hydrogen power?
It only requires moving water in order to work.
What are the advantages of hydrogen power?
– The use of hydrogen greatly reduces pollution. When hydrogen is combined with oxygen in a fuel cell, energy in the form of electricity is produced. – Hydrogen can be produced locally from numerous sources. – If hydrogen is produced from water we have a sustainable production system .
How does hydrogen power work?
Thermal Processes. Thermal processes for hydrogen production typically involve steam reforming,a high-temperature process in which steam reacts with a hydrocarbon fuel to produce hydrogen.
What is the power of hydrogen?
The pH of a solution is a measure of the molar concentration of hydrogen ions in the solution and as such is a measure of the acidity or basicity of the solution. The letters pH stand for “power of hydrogen” and the numerical value is defined as the negative base 10 logarithm of the molar concentration of hydrogen ions. pH = -log 10 [H +]
