Atomic Structure Flashcards
If you are given a mass spectrum
You can use isotope values
Calculating RAM from signals
- subtract any irrelevant groups
- divide by relative intensities
Like a ratio
Intensity / total intensities interested in
Orbital
An area of space where there is a high probability of an electron being found
Periodicity
Patterns in properties that repeat across different periods
E.g. • first ionisation energy • ion formulae • compound formulae • valence electron configuration
Ionic radius
Are they full?
Do they repel?
How does this affect the volume?
Noble gases
Too much energy is required, they cannot form ions
High energy electrons fired from an electron gun
Cause particles to lose an electron (1+ charged ions)
Remember to show the
1+ charge on species in a mass spectrometer
First ionisation energy differences when there are just more electrons in the same subshell?
Have you considered spin pairing?
if not, try greater nuclear charge with equal shielding
Graph showing conductivity of a period
Across across metals and then crashes to zero
