- c)Electrons in the inner shell only
- d)Electrons in outer most shell only
Correct answer is 'B'. Can you explain this answer?
Verified Answer
The atoms of different isotopes of same element differ from each other...
Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain.
In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.

The atoms of different isotopes of same element differ from each other...
Isotopes are atoms of the same element that have the same number of protons but a different number of neutrons. This means that isotopes have the same atomic number (number of protons) but different atomic masses (sum of protons and neutrons).
Explanation:
• Protons: The number of protons in an atom determines what element it is. All atoms of the same element have the same number of protons in their nuclei. Therefore, isotopes have the same number of protons.
• Electrons: Electrons are negatively charged particles that orbit the nucleus of an atom. The number of electrons in an atom is equal to the number of protons in the nucleus because atoms are electrically neutral. Therefore, isotopes have the same number of electrons.
• Neutrons: Neutrons are uncharged particles that reside in the nucleus of an atom. Isotopes of an element have different numbers of neutrons in their nuclei. This means that isotopes have different atomic masses.
• Inner Shell Electrons: The inner shell of an atom is filled with electrons that are closest to the nucleus. The number of electrons in the inner shell is determined by the atomic number of the element. Therefore, isotopes have the same number of electrons in the inner shell.
• Outermost Shell Electrons: The outermost shell of an atom is called the valence shell. The number of electrons in the valence shell determines the chemical properties of the element. Isotopes of an element have the same number of valence electrons.
Conclusion:
Hence, the correct answer is option B. The isotopes of the same element differ only in the number of neutrons present in their nuclei. All isotopes of an element have the same number of protons and electrons.

The atoms of different isotopes of same element differ from each other...
Isotopes are elements having same atomic number but different atomic mass We know no. of proton represent the atomic no. of the element So no. of proton cant change Also electron have negligible mass The only thing left which can produce difference in mass is neutron For example isotopes of carbon C12 , C13 , C14(radioactive) all hav same atomic no. 6 but different mass no. bcoz they hav different no. of neutron
