Chemistry

Question 1

Covelant bonds

Answer 1

Electrostatic attraction
Metals and non metals
Always on the outside shell

Question 2

Ionic Bonding

Answer 2

Between positively charged ions
Electrostatic attraction
Between metals and non-metals

Question 3

Metallic bonding

Answer 3

Electrostatic attractive force between conduction electrons

Positively charged electrons

Question 4

Transition metals

Answer 4

Centre of the periodic table
Compounds are catalysts
Often coloured
More than 1 ion

Question 5

Group 1 elements

Answer 5

Reactive and soft metals
Low density in water
Increasing reactivity because the outer electron is positioned further away from the nucleus

Question 6

Noble gases

Answer 6

No electron on the outer shell
Referred to as Group 0
All gases

Question 7

The halogens

Answer 7

Reactivity decreases as the outer electron is closer to the nucleus
Has 7 electrons in the outer shell

Question 8

Properties of Metals

Answer 8

Shiny
Hard
Bendy
Conductors of electricity

Question 9

Non-metals

Answer 9

Gases or liquids

Non-metals form a variety of different structures so have a wide range of chemical properties

Question 10

The periodic table

Answer 10

Vertical columns are called groups

Horizontal columns are called periods

Question 11

Structure of the atom

Answer 11

First shell: 2 electrons max.
Second shell:8 electrons max.
Third shell: 8 electrons max.

Amount of electrons on the outer shell determines the elements group
Amount of shells determine the period the element is in
