The Periodic Table

The periodic table is used a lot in chemistry. It has lots of information on it and if you know how to use it properly, it can really give you the edge when it comes to getting marks in the exam. Here are some handy tips on the importance of the periodic table.

Do I need to memorise the period table for GCSE Chemistry?

No! Unless you want to (seriously) impress someone, then you do not need to memorise the periodic table. However you do need to learn about it and be able to identify certain patterns and explain properties of some of the elements in it. Let's look at the groups first.

What are groups in the periodic table?

The groups are vertical columns that contain elements and are numbered from 1 to 8. In fact group 8 is more often called group 0. You’ll see the group numbers on the periodic table at the top of the columns. There are many elements however, that are not in groups. These are the transition elements and they are all metals. They do not have numbers at the top of their columns.

Which groups do I need to know about?

For GCSE Chemistry you will need to learn the features (we usually use the word properties) of group 1, 7 and 0. Once you learn these you can often apply the information to questions in exams.

Will I get a periodic table in my exam?

Yes. You should get a copy of the periodic table with your exam. Something that is often missed - there is a key on the periodic table that could help you with certain exam questions. The key tells you what the numbers linked to each element are. The bottom number, the atomic (proton) number, is useful because it tells you the number of protons in the nucleus of an atom. This then tells you the number of electrons (it's the same number).
