Electron Structure

Question 0

Define successive ionisation energy

Answer 0

Successive ionisation energy is the energy required to remove an electron from each atom in in turn

Question 1

define first ionisation energy

Answer 1

First ionisation energy is the energy required to remove one electron from each atom in one mile of gaseous atoms to make one mole of gaseous 1+ ion

Question 2

What are the factors that affect ionisation energy?

Answer 2

Atomic radius

Nuclear charge

Electron shielding

Question 3

State the number of electron in the first 4 shells

Answer 3

2, 8, 18 and 32

Question 4

What are the four types of orbitals

Answer 4

S, p, d and f- orbitals

Question 5

What are s orbitals

Answer 5

They are spherical shaped

They are from n= 1 and upwards
Each shell contains 1 s-orbital

So a total of 1 x 2 electrons in each she’ll

Question 6

What are p orbitals?

Answer 6

They are dumbbell shaped

In each shell , there are three

They are from n= 2 upwards

So a total of 2 x 3 = 6 electrons

Question 7

What are d and f orbitals?

Answer 7

D orbits are from n= 3 upwards
And each shell contains 5
So 5x2= 10 electrons

F orbitals are n= 4 and upwards, each shell contains 7 orbitals

7x2 = 14 electrons
