Red has the longest wavelength in visible light, about 700 nm, so the tiny particles of air, fog, smoke and dust scatter it the least.

The reactivity series lists metals from the most reactive to the least reactive, and potassium heads it because it loses its single outer electron most easily.

It gives the direction of the force, and so of the motion, on a current-carrying conductor placed in a magnetic field, which is exactly what turns the coil of a motor.

Combustion means burning in oxygen, and complete burning of methane gives carbon dioxide, water, heat and light. The equation is balanced: one carbon, four hydrogen and four oxygen atoms on each side.

The N shell is the fourth shell (n = 4), and the most electrons a shell can hold is given by the formula 2n², so 2 × 4² = 32.

In diamond every carbon atom is joined to four other carbon atoms by strong covalent bonds. These bonds point towards the corners of a tetrahedron and build a rigid three-dimensional network that runs through the whole crystal.

It is the standard set of rules used for reflection by spherical mirrors and for the mirror formula. Under this convention the pole of the mirror is the origin and the principal axis is the x-axis.

Early Mathura Buddhas show the right hand raised with the palm facing out, the gesture that says "fear not". The Mathura School flourished under the Kushanas in the first centuries CE, at the same time as the Gandhara school of the north-west.

Anabaena is a cyanobacterium, a prokaryote with no true nucleus, and all prokaryotes are placed in Monera. In R.H.

Nitrogen is an unreactive gas, so it drives the oxygen out of the packet and stops the oil in the chips from getting oxidised.

Violet has the shortest wavelength in visible light, so glass slows it the most and bends it the most. White light is a mix of seven colours, remembered as VIBGYOR.

Each metal here is paired with one of its best-known ores. Bauxite is hydrated aluminium oxide; alumina is refined from it and then broken down by electrolysis in the Hall-Héroult process.

The number 235 is the mass number and uranium's atomic number is 92, so the nucleus holds 235 minus 92, that is 143 neutrons.

The MSP is announced before sowing so that farmers know the lowest price at which the government will buy their crop.

When demand pushes the economy to produce more than it can at full employment, the extra demand only drives prices up.

A progressive income tax takes a bigger share when incomes rise and a smaller one when they fall, without any new decision by the government.

Elasticity measures how strongly the quantity demanded reacts to price, and zero means no reaction at all. Price elasticity of demand is the percentage change in quantity demanded divided by the percentage change in price.
