Question 1

Property of metal physical properties

Answer 1

Good conductor of electricity
Good conductor of heat
Shiny
High density(heavy for its size)
Malleable(you can hammer it into different shapes.)
Ductile(you can pull it into wires)
Sonorous(makes a ringing sound if you hit it)

Question 2

Physical properties of Non-metals

Answer 2

Poor conductor of heat
Poor conductor of electricity
Dull
Low density(light for its size)
Brittle(breaks easily)
Not sonorous

Question 3

Physical properties of group 1.

Answer 3

They are all soft metals that are easily cut with a scalpel or knife. At first the metals are shiny/but after they get tarnished because they react with oxygen. The metals become more reactive as you go down the group.

Question 4

Physical properties of group 7

Answer 4

They have a low melting point and boiling point. The melting and boiling points increase as you go down the group. The halogens become darker as you go down the group.

Question 5

What is a group?

Answer 5

In the periodic table the vertical columns are called group have similar properties. Going down a group there is a pattern in the properties such as melting point, boiling point and density

Question 6

What is a period?

Answer 6

The horizontal rows of the periodic table are called periods. Going across a period there are patterns in the properties of the elements.

Question 7

Hemical properties of group 1

Answer 7

They are soft
Mailable
Ductile
Very reactive
Melting decreases from top to bottom
As you go down the more reactive it becomes

Question 8

Chemical properties of group 7.

Answer 8

The colour gets darker as you go down. The reaction gets more vigorous from top to bottom.

Question 9

Physical properties of group 0

Answer 9

The properties of group 0 elements are they have a low melting and boiling point like many other gases they are colourless gases at room temperature.

Question 10

Chemical properties of group 0

Answer 10

They are unreactive gases.
