Question

Which element forms the maximum compound in chemistry
A. O
B. H
C. Si
D. C

Answer 1

Hint: Hydrogen denoted by the symbol, H is the first and fundamental element. Carbon is an abundant element in the Earth's crust, and the fourth most abundant element in the universe followed by hydrogen, helium, and oxygen.

Complete Step by Step Answer:
90% of all the atoms present in the universe are hydrogen atoms.
The chemist Lavoisier provided the name hydrogen. It earned its name from the Greek word “hydro” denoting water.
Hydrogen can constitute compounds with more electronegative elements, like halogens (F, Cl, Br, I), or oxygen.
In these compounds, hydrogen possesses a partial positive charge.
When H is bonded to a more electronegative element it takes part in a noncovalent bonding with another electronegative element with a lone pair through hydrogen bonding.
Hydrogen also constitutes compounds with less electronegative elements, such as metals and metalloids, where it carries a partial negative charge. These compounds are called hydrides.
Millions of hydrocarbons are figured out, and they are generally constituted by complex pathways that concern elemental hydrogen.
H can constitute bonds with all metals, metalloids, and nonmetals, group 18 is an exception it constitutes the utmost number of compounds.
So, option B is correct.

Note: Hydrogen forms an extensive collection of compounds with carbon called hydrocarbons. The study of the properties of hydrocarbons is called organic chemistry and their study of the ground of living organisms is called biochemistry. We go by the descriptions, "organic" compounds are only needed to include carbon. Yet, most of them also comprise hydrogen. It is the carbon-hydrogen bond that provides organic compounds with most of their chemical characteristics.
