1
Q

isotope

A

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

2
Q

What does RAM use?

A

weighted average of isotopic masses

3
Q

What does x-axis in mass spectrum show?

A

mass/charge ratio of different ions

4
Q

What does y-axis in mass spectrum show?

A

percentage abundance of ions

5
Q

absorption spectrum

A

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

6
Q

emission spectrum

A

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

7
Q

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

A

colors missing in an absorption spectrum

8
Q

quantized

A

can only change energy by discrete amounts

9
Q

Is the energy of excited electrons quantized?

A

yes otherwise would be continuous emission spectrum

10
Q

hydrogen spectrum visible light

A

electron falls to n=2

11
Q

hydrogen spectrum ultraviolet light

A

electron falls to n=1

12
Q

hydrogen spectrum infrared radiation

A

electron falls to n=3

13
Q

Why do lines converge at higher energies?

A

energy levels inside atom are closer together at higher energy
