Section 1: The Chemistry of the Elements
Introduction to the Chemistry of the Elements

In Lesson 1 we take an in-depth look at the Periodic Table and the arrangement of groups and periods.  There is a clear divide between the metals and non-metals, and we consider the differences between the two classified groups.  We then cover the chemical properties of the groups, and finish off with an explosive look at the Group1 (Alkali) metals!

00:26  The Periodic Table
04:25  Metals and non-metals
07:58  Groups and their chemical properties
13:50  Group 1 - The Alkali Metals

 

23:07

In this lecture we start by looking at Group 7 elements, or Halogens as they are more commonly known.  We cover displacement reactions involving the Halogens, and then move on to oxygen and how it is prepared in the laboratory.

00:22  Group 7 elements
04:40  Reactions of the Halogens
10:15  Halogen displacement reactions
13:10  Redox reactions and electrons - OILRIG
16:07  Gases in the atmosphere
17:37  Oxygen in the air
21.44  The preparation of oxygen in the laboratory

 

21:53

Lesson 4 continues with the chemistry of oxygen, and the formation of oxides.  We then look in some depth at the chemistry of carbon dioxide, including its role as a greenhouse gas.  There is then a brief introduction to acids, and their reactions with metals, and we finish off with hydrogen and a description of the tests for water.

00:43  Reactions of oxygen - oxide formation
04:15  Carbon dioxide - laboratory preparation
06:15  Carbon dioxide - physical and chemical properties
08:21  Carbon dioxide - uses
09:25  Carbon dioxide - as a greenhouse gas
11:15  Dilute acids
13:10  Acids and metals
16:30  The combustion of hydrogen
19:12  Testing for water
20:24

Lesson 4 begins with an explanation of what we mean by the term 'reactivity series' and how the order of metals in the series can be deduced through observations of their relative reactions with water and dilute acids.  The lesson then continues with a look at displacement reactions, and what we need to understand by the terms 'oxidation' and 'reduction'.  Finally we look at rusting as a practical example of oxidation.

00:32  What is the reactivity series?
01:39  Reactivity of metals with water
04:50  Reactivity of metals with dilute acids
06:25  Displacement reactions
11:00  Oxidation and reduction
16:10  Rusting

 

19:19

In our final lecture we look at chemical tests for cations, anions and gases.  The first section explains what we mean by the terms 'cations' and 'anions', with examples of both and lists of the more common ones.  Tests for both types of ions are then described with illustrated examples.  The last section looks at the tests for the more common gases.

00:30  Cations and anions
01:00  Examples of cations
02:30  Examples of anions
03:36  Common cations
04:30  Common anions
05:45  Tests for cations
11:05  Tests for anions
14:55  Tests for gases

Instructor Biography

Graham Bray, Director of STEM, East Sussex, UK

I have been a teacher in the UK for nearly 30 years, and am currently the Director of STEM (Science, Technology, Engineering and Maths) at a large comprehensive school in East Sussex. To bore you with the qualifications, I have a Joint Honours Degree in Botany and Zoology from University College, Cardiff, and a PhD in Biological Sciences from the University of East Anglia. I was also one of the first Advanced Skills Teachers in the South East of England.

I am a passionate believer in life-long learning, and I will do whatever I can to encourage learning for all ages. Using videos to enhance learning has great potential, and I try to exploit this through my websites.

On a personal level I am married to a primary school headteacher, and we have two grown-up daughters. When not creating videos or teaching I relax (!) by working out at the gym, watching rugby and football, and doing a little work around the garden.
