What is the periodic table?
A list of elements
2 of 19
What is an element made out of?
One type of atom
3 of 19
What are the two particles in the centre of the atom?
Neutron and Proton
4 of 19
Why are atoms neutral?
This is because the number of protons equals the number of electrons and their charges are equal and opposite
5 of 19
What is the atomic number?
The number of protons (and electrons)
6 of 19
How are elements arranged on the periodic table?
In order of their atomic numbers.
7 of 19
What is the mass number?
Proton and neutron
8 of 19
What are electrons in, in an atom?
Energy levels.
9 of 19
How do Group 1 react with water and oxygen?
They react quickly
10 of 19
Describe the nature of the noble gases?
They are unreactive because they have a stable outer shell.
11 of 19
Why are nitrogen and phosphorus both in Group 5 of the periodic table?
Because they have 5 electrons on their outer energy level

What are formed when a metal and non- metal react?
An ion
13 of 19
How does an ionic compound stay as it is?
The oppositely charged ions attract each other strongly - electrostatic forces.
14 of 19
What are formed when non-metals combine?
Covalent bonds?
15 of 19
What is the differences of a covalent bond and an ionic bond?
1. Only occur between non-metals 2. Sharing of electrons 3. Not charged
16 of 19
What does the chemical formula of a molecule tell us?
The number of atoms in the molecule
17 of 19
What happens to atoms during a reaction?
Atoms re arrange themselves to form new substances. They are neither created nor destroyed in a chemical reaction. mass=mass
