With an atomic weight of 7000100794000000000♠1.00794 u, hydrogen na di lightest element for di periodic table. Its monatomic form (H) na di most abundant chemical substance for di Universe, wey dey make up roughly 75% of all baryonic mass. Non-remnant stars dey mainly composed of hydrogen for its plasma state. Di most common isotope of hydrogen, wey dem dey call protium (name wey dem no dey use often, symbol 1H), get one proton and no neutrons.

Di universal emergence of atomic hydrogen first happen during di recombination epoch. At standard temperature and pressure, hydrogen na colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with di molecular formula H2. Since hydrogen dey easily form covalent compounds with most non-metallic elements, most of di hydrogen for Earth dey exist in molecular forms like for di form of water or organic compounds. Hydrogen dey play one particularly important role for acid–base reactions as many acid-base reactions involve di exchange of protons between soluble molecules. For ionic compounds, hydrogen fit dey as a negative charge (i.e., anion) when dem dey call am hydride, or as a positively charged (i.e., cation) species wey dem dey denote with di symbol H+. Di hydrogen cation dey write as if e dey composed of one bare proton, but for reality, hydrogen cations for ionic compounds dey always more complex species pass wetin dat go suggest. As di only neutral atom wey dem fit solve di Schrödinger equation analytically, study of di energetics and bonding of di hydrogen atom don play one key role for di development of quantum mechanics.

Answer di following questions:
1. Wetin be Hydrogen?
2. Wetin be im weight?
3. How much dey for air?
4. E dey toxic?
5. When e first happen?
6. E get taste?
7. E fit dey found for liquid?
8. E dey for space?
9. Who discover am?
10. When e discover am?
