Question 13

What is a isotope?

Answer 13

Same number of protons, different mass number, and different number of neutrons

Question 14

Definition of isotope

Answer 14

Different atoms of the same element with varying mass numbers and number of neutrons

Question 15

What are less common isotopes used as?

Answer 15

Tracers

Question 16

Why are rarer isotopes used as tracers?

Answer 16

They react the smae because they have the sname number of valence electrons.
They can be detected from the most common isotope.

Question 17

How do you differentiate between a rare isotop and a common isotope?

Answer 17

Through their mass and how radio active they are.
