Bromine water reacts with ethane as it is able to break open the double bond, forming 1,2-dibromoethane. This double bond is not present in ethane, so bromine water does not react with it. This reaction i...

To work out the shape of the SF6 molecule we can use a simple equation which allows us to work out the number of electron pairs. The equation is (old group + electrons donated +/- charge) / 2. If the char...

As you move across the period you are adding one more proton which increases the nuclear charge, you are also adding one more electron, however, the shielding provided by the extra electron is less than t...

This is due to the different numbers of electrons in each molecule and VSEPR (Valence Shell Electron Repulsion) theory. This theory states that as electrons are negatively charged, the valence electrons i...

Firstly, it's important to recognise that ionic compounds and metals are two different structures. Ionic compounds consist of positively charged ions and negatively charged ions held toge...
