Question

In a Bainbridge mass spectrometer positive rays of the same element produce different traces. The traces correspond to:

• A. isotopes
• B. isobars
• C. isotones
• D. none of the above

Answer 1

Answer: (A)

isotopes

In a Bainbridge mass spectrometer positive rays of the same element produce different traces. The traces correspond to isotopes. Isotopes are atoms of same element. They have same atomic number (nuclear charge) but different mass number (number of neutrons). Positive rays (or anode rays or canal rays) contains ions obtained by knocking out electrons from gaseous atoms.
