BLOCK 1 Electronic structure + massspec

Question 1

4s fills before 3d
apart from…

Answer 1

Chromium and Copper

Question 2

State all the parts of the mass spectrometer

Answer 2

• electron gun
• Electric field
• electromagnet
• sample chamber
• ion detector plate
• vacuum pumps

Question 3

what do vacuum pumps do?

Answer 3

Gets rid of all contaminating particles

Question 4

what does the electron gun do?

Answer 4

Produces high energy electrons, which collide with particles, therefore ionising them

Question 5

what does the sample chamber do?

Answer 5

Vaporises all sample particles

Question 6

what does the electric field do?

Answer 6

Sends positive ions in a straight line

Question 7

What does the electromagnet do?

Answer 7

Deflects positive ions into the ion detector plate

Question 8

What does the ion detector plate do?

Answer 8

Counts every particle, that’s hit it

Question 9

what charge does the ion detector plate have?

Answer 9

Negative charge to attract the positive ions

Question 10

How are ions separated

Answer 10

With an electromagnet of varying strengths.
larger ions = more difficult to deflect than smaller ones
