What is the strongest type of Intermolecular Force?
Hydrogen bonding
1 of 8
What is the third stage of the mass spectrometer?
Acceleration
2 of 8
Why is there a general increase in first ionisation energy across a period?
Because the number of protons increases, giving a stronger attraction to the outermost electron

Great for recap ! Thanks! 
But for question 2... the third stage of the mass spectrometer is Deflection not acceleration :)  
The ions are attracted to negatively charged plates... pass through slits which forms the ions into a beam. And then the beam of Ions is deflected :)

@Melissa

1. Vaporisation (turned to gas)

2.Ionisation (Made into ion)

3. Accelaration (ion sent off)
