Assertion: Isotopes are electrically neutral.
Reason: Isotopes of an element have equal number of protons and electrons.
Explanation:
Isotopes are atoms of the same element that have different numbers of neutrons in their nucleus. The number of neutrons in an atom does not affect its electrical charge because neutrons are electrically neutral. Therefore, the assertion that isotopes are electrically neutral is correct.
The reason given for this assertion is also correct. All atoms have an equal number of protons and electrons in order to maintain electrical neutrality. Protons have a positive charge, while electrons have a negative charge. The positive charge of the protons is balanced by the negative charge of the electrons, resulting in an overall neutral charge for the atom.
Since isotopes have the same number of protons as the original element, they also have an equal number of electrons. This maintains the electrical neutrality of the atom, regardless of the number of neutrons present.
Conclusion:
Both the assertion and the reason are true, and the reason provides the correct explanation for the assertion. Therefore, option A is the correct answer.
