Question

The name hydrogen was given by
A. Cavendish
B. Lavoisier
C. Urey
D. None of these

Answer 1

Hint: Hydrogen is the most prevalent element in the universe, and its name derives from the Greek terms hydro, which means water, and genes, which means to make. Dihydrogen is in its molecular form. It makes up 70% of the universe's entire mass. It is the solar system's primary component. The hydrogen-based element makes up the majority of the big planets like Jupiter and Saturn. It makes up 15.4% of the earth's crust and seas when combined.

Complete Step by Step Answer:
Hydrogen is the most prevalent element in the universe, and its name derives from the Greek terms hydro, which means water, and genes, which means to make. Dihydrogen is in its molecular form. It makes up 70% of the universe's entire mass. It is the solar system's primary component. Henry Cavendish, an English physicist, made the discovery of hydrogen in 1766. He called it "inflammable air." In 1783, French chemist Antoine Lavoisier gave it the name hydrogen.

The most common state in which hydrogen is in the form of a diatomic hydrogen molecule. There are three isotopes of hydrogen protium, deuterium and tritium. The electrical arrangement is the same for all three hydrogen isotopes. They have nearly identical chemical characteristics as a result. However, due to variations in their mass numbers, they have quite different physical characteristics. Protium is the most prevalent and widely distributed isotope of hydrogen among the three.
Hence, B. Lavoisier is the correct answer.

Note: One of the simplest elements on earth, hydrogen is an odourless, colourless, tasteless, and combustible gaseous material. The nucleus of a hydrogen atom contains a proton, a single positive electrical charge unit, and an electron, a single negative electrical charge unit, which orbits the nucleus. Under normal circumstances, hydrogen gas is a loose collection of diatomic hydrogen molecules.
