Question :

The following questions consist of two statement Assertion(A) and Reason(R) questions selecting the appropriate option given below:

(a) Both A and R are true and R is the correct explanation for A.

(b) Both A and R are true and R is not the correct explanation for A.

(c) A is true but R is false.

(d) A is false but R is true.

(i) Assertion(A) : Atom is electrically neutral.

(ii) Reason (R) : In an atom the negative and positive charges are equal in magnitude.

Explanation :

Atom is said to be electrically neutral . Since it has positive charges and negative charges in equal amount. Atom can be further broke down into three subatomic particles proton , electron and neutron . electron carry negative charge , proton carry positive charge and neutron is a chargeless particle . In an atom number of protons (positive charge) is equal to number of electrons (negative charge) . So , the atom is said to electrically neutral.

Assertion(A) and Reason(R) are correct and Reason(R) is correct explanation of Assertion(A).

Hence , Option(A) is the required answer.
