Q

Properties of alkali metals?

A

Soft, shiny metals
Good conductors of heat and electricity
Relatively low melting points
React vigorously with water
Form white products when combined with oxygen
Become more reactive moving down the group

17
Q

Properties of alkaline earth metals?

A

Similar properties to alkali metals but slightly less reactive

18
Q

Properties of the halogens?

A

Non-metals (apart from astatine a metalloid)
Highly reactive
Become less reactive going down the group
Can displace other less reactive halogens
Chlorine and fluorine are gases
Bromine is a liquid
Iodine is a solid

19
Q

Properties of noble gases?

A

Unreactive as they have a full outer shell of electrons

20
Q

Which side of the periodic table are metals found?

A

Left

21
Q

Which side of the period table are non-metals found?

A

Right

22
Q

Typical properties of metals?

A

Shiny solids (Mercury is the only metal that is liquid at room temperature)
They are ductile and malleable
High melting points
Good conductors of heat and electricity

23
Q

Typical properties of non-metals?

A

Dull
Brittle
Not malleable or ductile
Poor conductors
Low melting points

24
Q

What is a metalloid?

A

Have some properties similar to metals and some similar to non-metals
They are semiconductors as they can be modified to be conductors and insulators

25
Q

Around how many elements are essential in the human body?

A
