Atomic Abundance Flashcards
1
Q
5 steps of Mass Spectrometer
A
- vaporization (heat to gas)
- ionization (bombard w high energy electrons, get to single positive charge)
- acceleration (pass through slits to increase speed)
- deflection (passed over magnetic field, deflections proportional to charge/mass ratio, smaller masses deflect/turn more than heavy ones)
- detection (signals to recorder, look at graph)
2
Q
Avg atomic mass calculation
A
avg = (mass 1 * abundance) + (mass 2 * abundance) … mass 3 etc
3
Q
Percent abundance
A
The percent of natural occurring isotopes
