Atoms And Redox Tricky

Question 1

Isotope

Answer 1

Atoms of the same element with different numbers of neutrons and different masses

Question 2

Relative isotopic mass

Answer 2

The mass of an isotope relative to 1/12th the mass of an atom of carbon-12

Question 3

Relative atomic mass

Answer 3

The weighted mean mass of an atom of an element relative to 1/12th the mass of an atom of carbon-12

Question 4

What is a mass spectrometer used to do?

Answer 4

• Determining relative isotopic masses and relative abundances of an isotope
• using relative abundance of isotopes to calculate relative atomic mass of an element
