Atomic Structure

Question 1

What are the two exceptions when it comes to electronic structure?

Answer 1

Chromium: 1s2 2s2 2p6 3s2 3p6 4s1 3d5
Copper: 1s2 2s2 2p6 3s2 3p6 4s1 3d10

Question 2

Define ionisation energy

Answer 2

The first ionisation energy is the energy required to remove one mole of electrons from one mole of gaseous terms

Question 3

Define electron impact ionisation

Answer 3

Electrons are used to knock out an electron from a molecule or an atom

Question 4

Equation for electron impact ionisation

Answer 4

X(g) + e^- -> X^+(g) + 2e^-

Question 5

Equation for electrospray ionisation

Answer 5

X(g) + H^+ (g) -> XH^+ (g)

Question 6

What is different about the mass of an ion in electrospray ionisation?

Answer 6

Has a mass 1 higher than the atom/molecule (due to H^+)
