Module C4 - The Periodic Table

HideShow resource information
Name the 3 particles and their charges of an atom
Proton (+1), Neutron (0), Electron (-1)
1 of 15
What is the Mass number?
The total number of Protons and Neutrons
2 of 15
What is the Atomic Mass number?
The total number of Protons
3 of 15
Name the 5 types of elements on the periodic table
Reactive metals, Transition metals, Post-transition metals, non metals and noble gases
4 of 15
Why did Mendeleev leave gaps in his periodic table?
Because he predicted the properties of so far undiscovered elements.
5 of 15
How many number of electrons are allowed on each shell?
2,8,8. (Going from the inner shell to the outer shell).
6 of 15
What is an Isotope?
Isotopes are different forms of the same element, which have the same number of protons but a different number of neutrons.
7 of 15
What is Ionic bonding?
The loss or gain of electrons to form charged particles (+ or -).
8 of 15
Why does Ionic bonding happen?
So atoms have a balanced number of electrons e.g. 2,8,8 not 2,8,8,1.
9 of 15
What is a covalent bond?
When non-metal atoms combine together and they share pairs of electrons.
10 of 15
What colour does Lithium, Sodium and Potassium burn?
Lithium = Red, Sodium = Yellow/Orange, Potassium = Lilac.
11 of 15
Name three benefits of using a metal.
Strong, Good conductors and have a High melting point
12 of 15
What is thermal decomposition?
Thermal decomposition is when a substance breaks down into at least two other substances when heated.
13 of 15
Where does drinking water come from in the U.K?
Lakes, Rivers, Reservoirs and Aquifers.
14 of 15
Name the four steps water is put through to become purified?
1. Mesh 2. Sand filtration 3. Sedimentation 4. Chlorination
