Periodicity

Question 1

Volatile

Answer 1

a substance with a low BOILING point

Question 2

Why can metallic bonds be shaped

Answer 2

There are no bonds holding specific ions together so when the structure is bullet, metal ions can slide over each other.

So metals are malleable + ductile

Question 3

Malleable

Answer 3

Can be shaped

Question 4

Ductile

Answer 4

Can be drawn into a wire

Question 5

Factors that increase metal bp

Answer 5

• No. delocalised electrons/charge of ion
• SIze of ionic radius (small radius = greater charge density)

Question 6

Why metals conduct

Answer 6

Thermal - delocalised electrons can pass energy to each to each other (good thermal conductor)
Electricity - delocalised electrons can carry a current (good electrical conductors)

Question 7

First IE

Answer 7

Energy required to remove 1 mole of electrons from 1 mole of gaseous atoms

Question 8

Disproportionation

Answer 8

The same species is oxidised and reduced in the same reaction
