First, work out where the electron transfer is going to happen. Because it's ionic bonding we know 1 atom will lose electrons, and 1 will gain them. By using the electron shell's...

Group 7 of the periodic table contains all the elements known as halogens. They all have 7 valence electrons (hence group 7!) in their outer shell (insert diagram or prop to show what the outer shell sign...

First it is important to recognise that this is an ideal gas equation question – the exam boards love these so try to get used to spotting if you have the necessary quantities. This is a multi-step proble...

Group one elements are all metals. They are known as the Alkaline Metals. All of these element atoms have one electron on their outer shell. This means that, when they react, they lose this one electron t...

A hydrogen bond forms between the positive dipole of one molecule and the negative dipole of another molecule. They can be represented on a diagram with a dashed line perpendicular (at 90˚) to the bond an...
