Atomic Structure

Question 1

Special rule for the transition metals electron configuration

Answer 1

Loose from 4s then 3d

Question 2

Special rule for orbitals

Answer 2

4s level and 3d level overlap

Question 3

Which transition metals have unusual configurations

Answer 3

Cr and Cu

Question 4

Define ionisation energy

Answer 4

energy required to remove one mole of the outer most electrons from one mole of gaseous atoms or ions

Question 5

successive ionisation energies

Answer 5

Get greater each time due to there being the same number of protons but less electrons and so becomes harder to remove

Question 6

equation for time of flight

Answer 6

t=d/v

Question 7

number of particles equation

Answer 7

number of moles x avagadros constant

Question 8

define relative atomic mass

Answer 8

average mass of an atom of an element compared to the mass of a 1/12th of an atom of C12

Question 9

define relative molecular mass

Answer 9

average mass of a molecule of an element compared to the mass of 1/12th of an atom of C12
