Question

Identity which statement is true:
A. Isotopes of the same element have the same atomic number and mass number, but a different
number of neutrons.
B. Isotopes of the same element have the same mass number and different atomic numbers.
C. Isotopes of the same element have the same atomic number and different mass numbers.
D. Isotopes of the same element have the same number of neutrons and a different number of protons.

Answer 1

ans :C
same proton(atomic no.) and electron, diff neutrons
mass no= electrons + neutrons

Answer 2

Isotopes of the same element have the same atomic number and different mass numbers. Hence, option C is correct.

What are Isotopes?

Isotopes are defined as chemical species which have the same number of protons but differ in the number of neutrons.

It can also be said that they are the chemical species of the same element which have the same atomic number but have different mass numbers.

For Example, C12 and C14 are the isotopes of carbon elements, which have the same atomic number but a different mass numbers.

Hence, option C is correct.
