RAM and Mass Spectra

Question 1

isotope

Answer 1

atoms of same element that differ in mass (i.e. same number of protons, different number of neutrons)

Question 2

What does RAM use?

Answer 2

weighted average of isotopic masses

Question 3

What does x-axis in mass spectrum show?

Answer 3

mass/charge ratio of different ions

Question 4

What does y-axis in mass spectrum show?

Answer 4

percentage abundance of ions

Question 5

absorption spectrum

Answer 5

shows radiation absorbed as atoms move from lower to higher energy level

Question 6

emission spectrum

Answer 6

produced when an atom moves from a higher to lower energy level

Question 7

What do the colors present in an emission spectrum correspond to?

Answer 7

colors missing in an absorption spectrum

Question 8

quantized

Answer 8

can only change energy by discrete amounts

Question 9

Is the energy of excited electrons quantized?

Answer 9

yes otherwise would be continuous emission spectrum

Question 10

hydrogen spectrum visible light

Answer 10

electron falls to n=2

Question 11

hydrogen spectrum ultraviolet light

Answer 11

electron falls to n=1

Question 12

hydrogen spectrum infrared radiation

Answer 12

electron falls to n=3

Question 13

Why do lines converge at higher energies?

Answer 13

energy levels inside atom are closer together at higher energy
