The reactivity decreases down group 7 as the atomic radius increases, as the distance between the outer shell electrons and nucleus increases. As a result less energy is required to remove the outer elect...

Molecular formula: C₆H₆The Kekule structure (draw on whiteboard in session) - has the hexagonal shape of the ring, with a carbon=carbon double bond on every other carbon-carbon link....

Bonding between this compound will be ionic as potassium is a metal and sulphur is a non-metal.Therefore electrons are transferred from potassium to sulphur as metals must lose electrons to gain a full ou...

Balancing the equation means there must be an equal number of each element on both sides of the equation. In this case, we start with 8 carbon atoms on the left and just 1 on the right, so we can put 8 mo...
