Question

Which scientist established the name ‘hydrogen’ meaning water producer?
(A)- Robert Boyle
(B)- Henry Cavendish
(C)- Lavoiser
(D)- None of the above

Answer 1

Hint: Hydrogen was produced in 1671 while experimenting with iron and acids but it wasn’t recognized as a distinct element until 1766.

Step by step answer:
-Hydrogen is a chemical compound number of atomic number 1 with the symbol H and standard atomic weight of 1.008.
-Hydrogen is the lightest element in the periodic table.
-The most abundant chemical substance constituting roughly 75% of all baryonic mass in the universe is hydrogen.
-There are three isotopes of the element hydrogen known, that is hydrogen, deuterium, and tritium. All these isotopes have one single proton but differ in the number of their neutrons. Hydrogen has no neutron, deuterium has one neutron, and tritium has two neutrons. Out of which the most common isotope is hydrogen and the rarely used isotope is protium.
-Hydrogen is a colorless, odorless, tasteless, non-toxic, non-metallic, and highly combustible diatomic gas with the molecular formula ${{H}_{2}}$.
-Hydrogen gas was produced in the early 16th century artificially during the reaction of acids on metals. In 1766-81, the first person to recognize hydrogen gas as a discrete substance was Henry Cavendish. As the burning of hydrogen produces water, studying this property Antoine Lavoisier, a Greek scientist named hydrogen as ‘water former’ or ‘water producer’.

So the correct answer is option C.

Note: Hydrogen plays an important role in acid-base reactions because most of the acid-base reactions involve the exchange and transfer of protons between soluble molecules, In ionic compounds, hydrogen can be as a hydride, which is a negatively charged hydrogen anion, or as a positively charged cationic hydrogen.
