1

In the Periodic table how can we tell if an element is a metal or a non-metal?

Metals are on the left of the stepped lines and non-metals are on the right.

2

Name three typical properties of a metal

Any of these:
good conductor or electricity and heat
shiny
has a high density
malleable, ductile, sonorous

3

Name three typical properties of a non-metal

Any of these:
poor conductor or electricity and heat
dull
has a low density
brittle, non-sonorous

4

What is the definition of ductile and malleable?

ductile-Can be pulled into wires
malleable-Can hammer into different shapes

5

Finish the sentences
most metals have _ melting points, many non-metals have _ boiling points.

high
low

6

state the definition of a metalloid

An element that has properties between those of metals and non-metals.

7

Where are metalloids on the Periodic table?

Near/next to the stepped line

8

Metals and non-metals have _ chemical properties

different

9

metal:
magnesium + oxygen -> ?

magnesium oxide

10

non-metal:
sulfur + oxygen -> ?

sulfur dioxide

11

Many non-metal oxides are gases at _ degrees celsius

20

12

Finish the sentence:
In the periodic table, the vertical columns are called _. The horizontal rows are called _

groups, periods.

13

Where is Group 1 on the Periodic tabel?

far left

14

Why are Group 1 elements different to other metals?

They have lower melting points

15

State the definition of a physical property and a chemical property

Physical properties-describe things you can observe and measure
Chemical properties describe how substances take part in chemical reactions.

16

Name some characteristics of the Group 1 elements

have low melting and boiling points, they have low desnities and they are reactive

17

Group 1 elements react vigorously with water. Does the reactions get more vigorous from top to bottom or bottom to top?

Top to bottom

18

What is a displacement reaction?

When a more reactive element displaces a less reactive elements.

19

Name as many characteristics that Group 7 element might have.

Melting points and boiling points increase when going down the the Group. The colours of the elements get darker and more reactive.

20

Where is Group 7 on the Periodic table?

Second from the right.

21

Where is Group 0 on the Periodic table?

Furthest right.

22

What are the Group 0 elements called?

the noble gases

23

Name as many characteristics that Group 0 element might have.

They have low melting points and boiling points. They are colourless gases at room temp and are unreactive.
