What you'll learn

  • By the end of this course you will have received a thorough preparation in the principles of Chemistry. If you follow the course carefully the you should be looking forward to studying for your very first Chemistry exam - it's entirely up to you!

Course content

1 section • 7 lectures • 2h 8m total length

  • Introduction to Principles of Chemistry1:23
  • States of Matter and Atomic Structure38:33

    In this lecture we cover the basic differences between solids, liquids and gases.  We also look at atomic structure, and what information can be extracted from a knowledge of the Periodic Table.

    01:10  Solids, liquids and gases
    07:30  Evidence of particles
    10.50  Atoms and molecules
    11.30  Elements, mixtures and compounds
    13.50  Separation techniques
    19.10  Atoms and atomic structure
    23.35  Atomic mass and mass number
    25.35  Isotopes
    26.50  Relative atomic mass
    29.10  The Periodic Table
  • Relative Formula Mass and Chemical Equations29:22

    This lesson covers relative formula mass, including the use of the term 'mole' and how we carry out mole calculations.  We also then look at writing chemical equations to show the reactions being studied.

    00:40  Relative atomic mass
    02:42  Relative formula mass
    03:30  Chemical formulae
    07:36  The mole
    10:20  Mole calculations
    13:01  Using chemical symbols
    16:35  Chemical equations
  • Chemical Formulae13:44

    In lesson 3 we really focus on chemical formulae - how we can determine these experimentally, how we calculate the formulae of hydrated salts, and how we can work out the simplest or empirical formulae.  We finish this lesson with a look at molecular formulae.

    00:28  Finding chemical formulae - experimentally!
    02:14  Empirical formulae
    07:45  Water of crystallisation
    11:00  Molecular formulae
  • Reacting masses, Ionic and Covalent Bonding23:55

    Lesson 4 (also referred to as Lesson 3 Part 2) starts with an introduction to calculating reacting masses using knowledge from experimental data and chemical equations.  We then look at calculations involving molar solutions, moving swiftly on to consider ion formation in detail.  The lesson concludes with an introduction to ionic and covalent bonding.

    00:38  Calculating reacting masses
    04:34  Moles and molar solutions
    09:30  Ionic bonding and atomic structure
    11:45  Ion formation
    14:10  Ion formation and the Periodic Table
    15:25  Oxidation and Reduction (electron loss or gain)
    16:24  Ionic bonding
    18:25  Giant ionic structure
    19:17  Covalent bonding
    21:37  Giant covalent structures
    22:40  Properties of ionic and covalent compounds
  • Metallic Crystals and Electrolysis18:04

    The final lesson in this section begins with a look at the structure of metallic crystals and how the arrangement of particles affects the properties of metals.  This leads into a consideration of electrolysis, and we finish off with examples of electrolysis in action.

    00:35  Metallic crystals
    01:27  Metal properties
    02:43  Introduction to electrolysis
    05:50  Electrolyte or non-electrolyte?
    07:52  Electrolysis in a solution
    09:18  Electrolysis of brine (sodium chloride solution)
    11:40  Half-equations
    13:20  Electrolysis of molten lead bromide
    14:17  Other examples of electrolysis
  • Conclusion3:36
  • Section 1 Quick Revision Quiz

Requirements

  • There are no essential course requirements, just a desire to learn more about Chemistry and a willingness to make the necessary effort!

Description

This course is a comprehensive introduction to Chemistry, covering everything you will need to know as you prepare for possible future exams.  It doesn't matter how much, or how little, prior knowledge of Chemistry you've got as this course will take you through all the necessary stages.

The content is based on the International GCSE specification as followed by thousands of students around the world, and will prepare you thoroughly for progression to advanced programmes.

In Section 1, The Principles of Chemistry, there are five video lessons, each one lasting about 20 minutes. The first lesson introduces the states of matter and atomic structure.  In the next lesson we progress to relative formula mass and chemical equations - don't be put off by these as everything is very carefully explained!  Lesson 3 covers chemical formulae, and we progress in lesson four to look at reacting masses, ionic bonding and covalent bonding.  Lesson five wraps up this part of the course with metallic crystals and electrolysis.

 

Who this course is for:

  • This course is intended for :
  • students who wish to follow a career in the sciences or medicine and who require really clear chemistry instruction
  • students who may already be following a course but who need additional support in order to successfully progress
  • anybody with a genuine interest in learning about the first principles of Chemistry!
