Question

An atom does not carry any electric charge because it __________.
A.Has an equal number of charged and non-charged particles
B.Has neutrons in their nuclei
C.Has an equal number of electrons and protons. Hence positive and negative charge gets neutralized
D.Has an equal number of neutrons and protons

Answer 1

Hint: We have to know that an atom is the littlest unit of standard matter that frames a chemical species. Each solid, liquid, gas, and plasma comprises either neutral particles or particles that are ionized. Atoms are of very small size, ordinarily around
$100$ picometers across.

Complete answer:
Each atom is made out of a nucleus (core of an atom) and a minimum of one electron bound to the core. The core comprises a minimum of one proton and several amounts of neutrons. Just the most well-known variety of hydrogen contains no neutrons. Over $99.94\% $ of a particle's weight is in the core. The protons exhibit positive electric charge, the electrons exhibit negative electric charge, and the neutrons exhibit no electric charge. Assuming the quantity of protons and quantity of electrons are equivalent, the atom becomes neutral. On the off chance that an atom contains more or less electrons than protons, it exhibits general negative or positive charge, individually – such particles are known to be ions.
We have to know that the electrons of an atom are drawn to the protons in a nuclear core through the electromagnetic force. The protons and neutrons in the core are drawn to one another by the nuclear force. We have to know atoms do not exhibit any electric charge as they contain equal amounts of electrons and protons. So, the positive charge and negative charge get neutralized.

Option (C) is correct.

Note:
We have to know that when we compare the atomic size, the size of subatomic particles could be less. We have to know that an atom has three subatomic particles namely electrons, neutrons, and protons. We have to know the electron contributes to the volume of an atom and mass of an atom is contributed by protons and neutrons.
