B) Isotopes have the same number of protons but have different numbers of neutrons.
C) Isotopes have the same atomic number but have different mass numbers.
Dall of the above

Answer 1

The correct option is d) all of the above.

Explanation:

• In the field of chemistry, isotopes can be described as elements that have the same atomic number but different mass number.
• As the atomic number is same, these elements have the same position on the periodic table.
• Isotopes differ from each other because their nucleon number or mass number is different.
• Hence, all of the above options are correct.
