Groups

Question 1

Name 3 element in group 0

Answer 1

Helium
Neon
Argon

Question 2

Why is helium different to the rest of the element in group 0

Answer 2

Helium only has two electrons on its outer shell wheat as the others have eight

Question 3

What happens to the boiling point as u go down the group

Answer 3

The boiling point gets higher

Question 4

Name 4 properties of group 1 elements

Answer 4

They are metals
They have a low density
Form ions with a charge of +1
React with chlorine to form solid ionic chlorides

Question 5

What happens as you go down group 1

Answer 5

Gets more reactive and the the melting and boiling points get lower

Question 6

Properties of transition metals

Answer 6

Have higher densities
Have higher melting points and boiling points
Are stronger and harder
Are much less reactive with oxygen and halogens

Question 7

What is ionic bonding

Answer 7

When there is an electrostatic attraction between a positively charged ion and negatively charged ion

Question 8

What is covalent bonding

Answer 8

When a non metal and non metal join together, sharing electrons

Question 9

What is metallic bonding

Answer 9

Where the atom lose their outer shell electrons forming ions
The ions will be in a 3d arrangement called LATTICE
metallic bonding only occurs in metals and alloys

Question 10

State what groups lose and gain electrons

Answer 10

Group 1- lose 1 electron to form +1 ions
Group 2- lose 2 electrons to form +2 ions

Group 6 gain 2 electrons to form -2 ions
Group 7 gain 1 electron to form -1 ions
