4 of 26
What contains the protons and the neutrons?
The protons and neutrons are located in the nucleus
5 of 26
Where are electrons found?
Electrons are found in the outer shell
6 of 26
What links protons and electrons?
The number of protons equals the number of electrons
7 of 26
What are isotopes?
Isotopes are the same as normal atoms but they contain extra neutrons
8 of 26

The AR of carbon is 12
9 of 26
Who invented the periodic table?
Mendeleev invented the Periodic table
10 of 26
In what order is the periodic table?
The periodic table is arranged in order of increasing atomic number
11 of 26
How do simple ions form?
Simple ions form when atoms lose or gain electrons
12 of 26
What is ionic bonding?
Ionic bonding is the transfer of electrons from a metal to a non-metal
13 of 26
What is the structure of an ionic compound?
Ionic compounds have a regular lattice structure
14 of 26
Describe the melting and boiling points of an ionic compound
Ionic compounds have high melting and boiling points due to strong attraction between the ions
15 of 26
Do ionic compounds conduct electricty
Ionic compounds do not conduct electricity because the ions are fixed in place
16 of 26
Describe a covalent bond
A covalent bond is a strong bond that forms when a pair of electrons is shared between two atoms
17 of 26
Describe the melting and boiling points of simple molecular substances
The melting and boiling points of covalent compounds are low because weak intermolecular forces
18 of 26
Describe the bonds of a giant covalent structure
In a giant covalent structure, all the atoms are bonded to each other by strong covalent bonds
19 of 26
Describe the melting and boiling points of a giant covalent structure
In a giant covalent structure the melting and boiling points are very high because lots of energy is needed to break the bonds
20 of 26
State 3 carbon-based giant covalent structures
3 carbon-based giant covalent structures are graphene, graphite and diamond
21 of 26
What do fullerenes form?
Fullerenes form spheres and tubes made of mainly hexagons
22 of 26
Describe the electrons in metallic bonding
The electrons in the outer shell of the metal atoms are delocalised due to strong electrostatic attraction between the positive metal ions and the shared negative electrons
23 of 26
What is always conserved in a chemical reaction
Mass is always conserved in a chemical reaction
24 of 26
What is a mole?
A mole is the name given to a large number of particles
25 of 26
What is the formula for moles
The formula for moles is Mass (g) / Mr/Ar
