Isotopes

Question 1

What are isotopes?

Answer 1

atoms with the same number of protons, but different number of neutrons

Question 2

How are different isotopes different from each other?

Answer 2

they have different masses

Question 3

What can the mass number of an isotope be referred to as?

Answer 3

relative isotopic mass

Question 4

What properties do isotopes have in common?

Answer 4

they have the same chemical properties - same electronic structure

Question 5

What similar properties do isotopes have?

Answer 5

very similar physical properties

Question 6

What does mass spectroscopy show?

Answer 6

the existence of isotopes and their relative abundances

Question 7

Where is the relative atomic mass (Ar) shown?

Answer 7

in the mass number

Question 8

What does the mass spectroscopy show??

Answer 8

in the whole universe, every sample of chlorine that we take and put onto the mass spectrometer, it shows us that out of all chlorine, only 75% of all chlorine is chlorine 35 - it is a common isotope, and 25% of chlorine tested is chlorine 37
