The nuclear atom Flashcards
1
Q
Isotopes
A
Atoms of the same element with the same number of protons but different number of neutrons
2
Q
Physical properties that vary among isotopes of the same element
A
- Density
- Diffusion rate
3
Q
Relative atomic mass
A
Average of the masses of the isotopes of an element
4
Q
Isotopic mass
A
Mass of one isotope
5
Q
How does a mass spectrometer work ( 5 steps) ?
A
- Sample injected through inlet
- Heater vaporizes sample
- Electron beam ionises sample
- Particles accelerated into magnetic field
- Magnetic field seperates particles based on mass/charge ratio
Lightest particles deflected most
Heaviest particles deflected least
