Atomic Structure

Question 1

If you are given a mass spectrum

Answer 1

You can use isotope values

Question 2

Calculating RAM from signals

Answer 2

• subtract any irrelevant groups
• divide by relative intensities

Like a ratio

Intensity / total intensities interested in

Question 3

Orbital

Answer 3

An area of space where there is a high probability of an electron being found

Question 4

Periodicity

Answer 4

Patterns in properties that repeat across different periods

E.g. 
• first ionisation energy 
• ion formulae 
• compound formulae 
• valence electron configuration

Question 5

Ionic radius

Answer 5

Are they full?
Do they repel?
How does this affect the volume?

Question 6

Noble gases

Answer 6

Too much energy is required, they cannot form ions

Question 7

High energy electrons fired from an electron gun

Answer 7

Cause particles to lose an electron (1+ charged ions)

Question 8

Remember to show the

Answer 8

1+ charge on species in a mass spectrometer

Question 9

First ionisation energy differences when there are just more electrons in the same subshell?

Answer 9

Have you considered spin pairing?

if not, try greater nuclear charge with equal shielding

Question 10

Graph showing conductivity of a period

Answer 10

Across across metals and then crashes to zero
