Question

The lowest grading level of matter are - a) Subatomic level b) atomic level c) molecular level d) electrons ​

Answer 1

Answer:

The lowest grading level of matter is atomic level.

Therefore, the option (b) is correct.

Explanation:

In chemistry, any entity that cannot be divided into smaller constituent entities is known as the smallest unit of matter. The mandatory condition is that the chemical properties of an element should be retained.

• Atom:- Atom is an elementary unit of a matter. The electrons, protons, and neutrons are the basic particles that make up an atom. Though atom can be divided into smaller components, none of them keep the chemical properties of the matter.
• Molecule:- Molecules are a group of atoms which are bonded together by chemical bonds. Molecule can be further divided , so they are not smallest unit of matter.
• Electron: It is the subatomic particle of an atom. But electrons cannot hold to its chemical properties. For example, an electron from a oxygen atom will be similar to an electron from an hydrogen atom.

Therefore, the atomic level is the lowest grading level of matter.
