Atomic Abundance

Question 1

5 steps of Mass Spectrometer

Answer 1

1. vaporization (heat to gas)
2. ionization (bombard w high energy electrons, get to single positive charge)
3. acceleration (pass through slits to increase speed)
4. deflection (passed over magnetic field, deflections proportional to charge/mass ratio, smaller masses deflect/turn more than heavy ones)
5. detection (signals to recorder, look at graph)

Question 2

Avg atomic mass calculation

Answer 2

avg = (mass 1 * abundance) + (mass 2 * abundance) … mass 3 etc

Question 3

Percent abundance

Answer 3

The percent of natural occurring isotopes
