Electronegativity is the measure of how strongly an atom attracts a bonding pair of electrons to itself. As group 7 is descended, the electronegativity decreases. This is because the size of the halogen a...

With these sort of questions, it's important to firstly think about what type of bonds make up the structure of the element. For this example, they both have metallic bonds which hold the structures toget...

Alkenes are more reactive due to the presence of a carbon carbon double bond (always important to state what the double bond is between or may not get the marks!). This is because the carbon carbon double...

Water has strong intermolecular hydrogen bonds that hold the water molecules close together, making it very dense. As water freezes, the hydrogen bonds move further apart as it forms a hexagonal lattice. ...

Optical isomers are a form of stereoisomers which are chemical species with the same structural formula, but have a different arrangement of atoms in 3-dimensional space. Optical isomers are characterised...
