Structural isomers These are compounds with the same number and type of atoms but the atoms are bonded in different
One of the best aspects of Chemistry A level is that you get to do lots of practical work 😎.
Continue readingPractical techniques are not just for the lab!
when your answer is in fact just your working out … This is without doubt the most frustrating thing examiners
The coordination number of a complex is the number of atoms making coordinate or dative covalent bonds to the central
d-block metal cations readily form complexes with ligands – neutral molecules such as water or anions such as the chloride
I offer 1:1 online chemistry tuition for students who need a confidence boost, help with exam technique or a crash
The transition metals are d-block elements (Groups 3-12 of the Periodic Table) whose atoms have a partially filled d-orbital or
