Well all will be revealed in this Earth themed podcast!
You may have heard of a price comparison site, well this is a bond comparison podcast! A neat little sound bite that summarises all the bond types, structures and physical properties. Find out the similarities and differences between covalent bonds, ionic bonds and metallic bonds. Not only that but find out how the structure affects physical properties and when you should talk about intermolecular forces when explaining melting and boiling points. All this and some example questions for you to have a crack at! Brilliant!
Do you have a steely determination to succeed in Chemistry? Well this podcast on metallic bonding will help you to succeed! Listen in to find out about what a metallic bond is and find out about the physical properties of melting and boiling points, malleability, ductility, strength and electrical and thermal conductivity. There is also a link with toast and jam! Seems odd but take a listen to find out more.
Watch out James Bond there is a new bond on the scene - POLAR BOND! Well at least in this podcast! Take a listen to find out what this polar bond is what electronegativity is. Explore the attractive world of intermolecular forces such as van der waals, dipole dipole and hydrogen bonding. Find out why these are so important when trying to explain physical properties of compounds. Stick with it, it will be worth it!
This podcast contains one of the most precious minerals on Earth! Yes, get your ear full of covalent molecules such as diamond, graphite, crystal and.... sewer gas! The variety of covalent molecules!

As usual it is packed with try it yourself questions to make sure you undersatnd the stuff! Now that's handy!
Just like a country has an economy, Chemistry has one too, called the atom economy. Let your brain absorb the wonders of this as well as percentage yield and empirical formula. Just to give you a little insight, you will find out how to calculate them all with little tips to help you grab all the marks in the exam. Not only that, but there are links to industry, highlighting the importance of yield and atom economy. Certainly not economical with the chemistry here!
Trying to titrate tests a titrator's time! Say that quick 3 times! Thankfully titrations doesn't have to be as difficult as that! In this podcast you will find out what a titration is as well as the reasons why we do specific things when doing a titration such as why we swirl the flask during a titration. All these are common 'How Science Works' concepts and vital for your practical exams!
