Question

Mass spectrograph helps in the detection of isotopes because they:

• A. have different atomic masses
• B. have same number of electrons
• C. have same atomic number
• D. have same atomic masses

Answer 1

The correct option is A have different atomic masses

Mass spectrograph helps in the detection of isotopes because they have different atomic masses.
Isotopes of an element have same atomic number but different mass number. They have a same number of electrons and the same number of protons but a different number of neutrons.
