Periodicity

Question 1

What is ionisation energy

Answer 1

The energy required to remove the most loosely held electron form one mole of gaseous atoms to form one mole of gaseous 1+ ions

Question 2

Factors that affect ionisation energy

Answer 2

Atomic radius
Nuclear charge
Shielding

Question 3

As you go down the group what happens to ionisation energy

Answer 3

Is decreases

Question 4

What happens in successive ionisation energies

Answer 4

Energy required increases, between shells = large increase

Question 5

Trends in ionisation across the period

Answer 5

General increase across subs hell but 2-3 down (subs hell) 5-6 down (repulsion)

Question 6

What are melting points governed by

Answer 6

Bonding
