All the following are major pollutants of ground water except CHLORINE FROM DRINKING WATER.

Ground water refers to the water source underneath the earth surface. This water source is very important to humans and plants and it is used for various purposes. The ground water source can be contaminated by pollutants such as fertilizers, pesticides, chemicals, radioactive wastes, etc.

Chlorine from drinking water can not contaminate ground water source, this is because, the amount of chlorine added to drinking water is very small and quite safe for human consumption. Apart from this, the chlorine usually dissipate from water few hours after its addition. Thus chlorine from drinking water does not pollute ground water sources.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
