simplified metals and non metals

Question 1

characteristics of a non metal

Answer 1

Poor conductors of heat and electricity

Dull in their appearance

Weak and brittle

can be solids liquids and gases at normal temperature

Question 2

characteristics of a metal

Answer 2

They have high melting points and boiling points

metals are solids at normal temperature except mecrury which is a liquid

They are good
conductors
of heat and electricity

They are shiny in their appearance and often grey

Question 3

The reactivity series generally means

Answer 3

the nearer the metals are to the top, the more rapidly they react

Question 4

metal+ water—>

Answer 4

metal hydroxide+ hydrogen

Question 5

metal + steam—>

Answer 5

metal oxide+ hydrogen

Question 6

metal + acid—>

Answer 6

salt + hydrogen

Question 7

metal + oxygen , what is called?

Answer 7

corrosion, a slow reaction,produces a thin layer of metal oxide making the surface look dull instead of shiny

e.g magnesium and aluminium and lead

Question 8

what cant react with corrosion

Answer 8

metals like gold and platnuim which are at the bottom of the reactivity series so they do not corrode at all
