Question

Particles that mostly affect material properties:

• A. neutrons
• B. protons
• C. electrons
• D. valence electrons

Answer 1

The correct option is D

valence electrons

The correct option is (D):

Explanation for the correct answer:

Valence electrons:

1. It basically refers to one or more than one electrons present in the outer shell of an atom which is responsible for the chemical properties of the atom.
2. These valence electrons will affect the material properties of the atoms as the number of valence electrons will cause the atom to be unreactive or highly reactive.

Explanation for the incorrect answer:

Option (A):

Neutrons:

1. It is basically a subatomic particle that is found in the nucleus of every atom except the Hydrogen atom.
2. These are actually the primary constituents of the atomic nuclei.
3. And also they do not affect the material properties of the atom.
4. Hence, this option is incorrect.

Option (B):

Protons:

1. This is basically a subatomic particle that is found in the nucleus of every atom.
2. This is the positive charged elementary particle.
3. And also they do not affect the material properties of the stable atom.
4. Hence, this option is incorrect.

Option (C):

Electrons:

1. This electron is actually the negatively charged subatomic particle.
2. It is the smallest particle that makes up the atom.
3. And also the do not affect the material properties of the atom.
4. Hence, this option is incorrect.

Therefore, the correct option is (D): Valence electrons.
