Topic 4 - Metals In The Periodic Table

Question 0

Most metals are what type of metal?

Answer 0

Transition metal

Question 1

Two properties of metals and give examples of each

Answer 1

Malleable - bridges and car bodies

Good conductors of electricity - electrical wires

Question 2

Properties of transition metals

Answer 2

High melting points

Form colourful compounds

Question 3

What gives the properties to an element?

Answer 3

Their structure of atoms in the metal

Question 4

How are atoms held together?

Answer 4

Metallic bonds

Question 5

What does metallic bonding give the metal?

Answer 5

A giant structure consisting of positive ions and free electrons

Question 6

Why do the electrons move more freely in a metal?

Answer 6

Metallic bonds allow the outer electron(s) of each atom to become delocalised (move more freely)

Question 7

Why are metals good conductors of electricity

Answer 7

Because the electrons move freely through the structure

Question 8

Describe alkali metals

Answer 8

Soft

Low melting points

Question 9

How do alkali metals react with water?

Answer 9

React vigorously to form HYDROXIDES

Question 10

The elements in group 1 get more reactive as the…

Answer 10

Atomic number INCREASES

Question 11

What is chlorine like a room temperature?

Answer 11

Fairly reactive, poisonous, dense-green gas

Question 12

What is bromine like at room temperature?

Answer 12

Dense, poisonous, orange liquid

Question 13

What is iodine like at room temperature?

Answer 13

Dark grey crystalline solid

Question 14

Halogens react with metals to form what?

Answer 14

Metal halides

Question 15

Halogens can react with hydrogen to form what…

Answer 15

Hydrogen halides

Question 16

Properties of noble gases

Answer 16

Inert, colourless gases

Question 17

What does inert mean?

Answer 17

Don’t react much or at all

Question 18

What makes a metal inert?

Answer 18

When they have a full outer shell which means they are NOT desperate to give up or gain electrons

Question 19

An experiment to discover noble gases?

Answer 19

Fractional distillation of air

Question 20

Everyday uses of noble gases?

Answer 20

• Argon = provides an inert atmosphere = in filament lamps (light bulbs) because it is non-flammable
• argon = metals that are being welded = inert atmosphere stops hot metal reacting with oxygen
• Helium = airships
• Helium = party balloons = helium has lower density then air which makes them foat

Question 21

Boiling points and densities of noble gases:

Answer 21

Increase as you go down the group
