The smallest unit of matter with unique characteristics is

a. an electron.
b. a molecule.
c. an atom.
d. a proton.

Expert Solution & Answer

Summary Introduction

Introduction:

Atom is a simplest unit of matter composed of particles like electrons, neutrons and electrons. Protons are positively charged particles in the nucleus; electrons are present in the outer orbitals and contain a negative charge. Neutrons do not possess any charge and are present in the nucleus.

Answer to Problem 1MCQ

Correct answer:

Simplest unit of matter with unique characteristics is called as an atom.

Therefore, option (c) is correct.

Option (c) is given as “an atom”.

Explanation of Solution

Justify the reason for the correct statement:

As the atom is the smallest unit of matter and it cannot be divided further. Therefore, it exhibits unique characteristics with the presence of charged particles inside it.

Hence, option (c) is correct.

Justify reasons for incorrect statements:

Option (a) is given as “an electron”.

An electron consists of a negative charge and these particles are present in the outer orbital. Hence, it is a wrong answer.

Option (b) is given as “a molecule”.

A molecule is composed of various atoms. Hence, it is a wrong answer.

Option (d) is given as “a proton”.

A proton is a positively charged particle present in the nucleus. Hence, it is a wrong answer.

Hence, options (a), (b), and (d) are incorrect.

Conclusion

Atom is a substance which cannot be broken into smaller parts, therefore, it is considered the smallest unit of matter.
