Question

Statement I: A neutral atom carries no net charge.
Statement II: An atom that has equal number of protons and electrons is called a neutral atom.

• A. Statement I is true and statement II is not the correct explanation.
• B. Statement I is true and statement II is false.
• C. Statement I is false and statement II is true.
• D. Statement I is true and statement II is the correct explanation.

Answer 1

The correct option is D Statement I is true and statement II is the correct explanation.

$\bullet$ Electron, proton and neutron are the subatomic particles of an atom. A proton carries a unit positive charge, while a electron carries a unit negative charge. A neutron carries no charge.

$\bullet$ The number of protons is equal to the number of electrons in a neutral atom.

$\bullet$ The charge of protons is balanced out by electrons in a neutral atom. Thus, it carries no net charge. Hence, statement I is true and statement II is the correct explanation.
