2 Mark for order 3 for correct bondIt is important to think about the bonds even if you are unsure about the order as you can still get 3 marks.Think about the bonds:Water, covalent bond (h_{2 <...}

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...

Both of these compounds are made purely of carbon. The differences come in the way in which the atoms are bonded together and the properties that this creates.In diamond, each atom is covalently bonded to...
