(In session I would begin by drawing a box-plot diagram and seeing if a student can also covert their data into a box-plot)There are 5 key points to a box-plot. You have the minimum value, lowest quartile...

If f(x)= 5 - x then f(2x)= 5 - 2x If g(x)= 3x + 7 then g(x-1)= 3(x-1) +7 = 3x - 3 + 7 = 3x +4
So f(2x) + g(x-1) = 5 - 2x + 3x + 4 = 9 + x

Graphite has a giant covalent structure where each carbon atom is covalently bonded to three other carbon atoms. Each carbon atom also has one delocalised electron which can flow freely through the struct...

Ionisation energies decrease going down group 1, firstly since the number of shells in the atom increases so the atomic radius is increased. There are also more electrons between the positively charged nu...
