Nitrogen

• Nitrogen is used as a refrigerant. When it is in a liquid form nitrogen is very cold. Scientists use that cold nitrogen to keep things frozen.

Nitrogen

• Even though we breathe oxygen from the air, did you know that over three quarters of the air is made up of nitrogen? Let's say you had one hundred pennies. Take 78 pennies and put them to the side. That's how much nitrogen is in the air.

Nitrogen

• Plants need nitrogen to grow. They get the nitrogen out of the soil that they grow in. The nitrogen is sucked in through the roots and pumped all the way up to the leaves. That's a long way if that tree is fifty feet tall. This process is called Nitrogen Fixation

Phosphorus

Phosphorus

• You can find lots of phosphorus in fireworks. When phosphorus gets hot it burns really brightly. The bright sparks and flashes are usually because of that phosphorus.

Phosphorus

• Phosphorus is a very important element in fertilizers. Plants need small amounts of phosphorus to grow up healthy. People also need phosphorus and they get it by eating plants.

Antimony

Antimony

• Antimony can be found in soils, waters and air in very small amounts. Antimony will mainly pollute soils. Through groundwater it can travel great distances towards other locations and surface waters. Labortary tests with rats and rabbits have shown us that relatively high levels of antimony may kill animals.

Bismuth

Bismuth

• Bismuth is also used extensively in cosmetics. Bi-citrate is used in Hair Coloring Dyes. These dyes help improve hair color and helps stabilize the hair. Bismuth is also used in makeup such as skin toners

Bismuth

• Bismuth is in alloys that make up automatic sprinklers and alarms. These alloys help create electric fuses that create those alarms and sprinklers.

Bismuth
