Look up all the halogens, give their name and formula. Describe what each one looks like under normal conditions.
Halogens contain salts and they are:
1. Flourine F Normal Conditions- Gas
2. Chlorine Cl Normal Conditions- Gas
3. Bromine Br Normal Conditions- Liquid
4. Iodine I Normal Conditions- Solid
5. Astatine At Normal Conditions- Solid
Give the names and formulas of three compounds that contain one element from the Noble Gas family.
1. Helium He
2. Neon Ne
3. Argon Ar
4. Krypton Kr
5. Xenon Xe
6. Radon Rn
Look up the elements in group 15 from period 2 - 5, give the name and symbol of each. Give a biological use for each (click on the element and then on the term "biology" in the margin).
1. Nitrogen N nitrogen is a key component of biological molecules such as proteins (which are made from amino acids, and nucleic acids. The nitrogen cycle in nature is very important.
2. Phosphorus P phosphorus is a key component of biological molecules such as DNA and RNA. Phosphorus is a component of bones, and teeth, and many other compounds required for life. Chronic poisoning of people working unprotected with white phosphorus leads to necrosis of the jaw ("phossy-jaw").
3. Arsenic As arsenic, despite its poisonous reputation, may be a necessary ultratrace element for humans. It is a necessary ultratrace element for red algae, chickens, rats, goats, and pigs. A deficiency results in inhibited growth.
4. Antimony Sb In small doses it is said to stimulate the metabolism
Look up the elements in group 2 from period 2 - 5, give the name and symbol of each. Give information about how each is commonly found in NATURE (if you were walking down the street and picked some off the ground, in what form would it be? Would you have to be walking in a certain part of the world?)
1. Beryllium Be In Egypt in a rocky area
2. Magnesium Mg- Oceans and streams
3. Calcium Ca In limestone and in oceans/streams
4. Strontium Sr
