Atomic Structure: Mass Spectrometer (GRAPHS).

Question 1

What do the peaks of the graphs tell us?

Answer 1

= How many isotopes an element has

Question 2

How can we calculate the percentage abundance of the isotopes if we are given the r.a.m and relative isotopic mass? (ALGEBRA)

Answer 2

= E.G: Boron has a Ar of 10.8/
= it has 2 isotopes B(10) and B(11)
= calculate percentage abundance
(10x X) + (11 x 1 -X)
and solve the equation.

Question 3

How can we calculate the percentage abundance of the isotopes if we are given the r.a.m and relative isotopic mass? (NUMBER LINE)
= only for 2 isotopes

Answer 3

= Distance from the isotope to the AR
= DItsnance of both isotopes
= both divided by total distance.
