~Hydrogen atom which has no neutrons and only 1 proton and 1 electron. Why no neutrons? There is only one proton and thus a neutron is not needed to stop the nucleus from falling part due to repelling nature of protons.
The ground state energy level of the electron in a hydrogen atom is 13.6 eV, which is equivalent to an ultraviolet photon of roughly 92 nm.

~I am discovered by the lovely gentleman Henry Cavendish, in 1766. He was the one who recognized me even though Robert Boyle through a experiment already find out me. But it was Henry who recognized me as an element!Henry described me as "inflammable air from metals".
~I am very useful on Earth, do you know i am used in your everyday live? over 9 million tons of hydrogen are produced in the U.S. each year and 3.2 trillion cubic feet are used to make many common products
~ Watch Make Hydrogen with just a metal and an Acid
~run the currents into the water and seperate the Hydrogen and Oxygen
