The answer is too long for Wiki Answers; please read a book of general chemistry.
it is a elements in periodic table and it is a metals
Yes, Chlorine is an element in the periodic table of elements. It has a variety of uses and is both a poisonous gas and one of the elemental ingredients of the common table salt.
Elements: iron, nickel, uranium, astatine, lanthanum and the others up the atomic number 118. Fot the applications hundred of volumes can be writed !
The periodic table should be memorized because it will make you know the symbols without searching for them all of the time. If you are in school, it is very likely that you will be tested on the table.
life on earth is mostly made out of C H N S P and to a lesser degree Ca Na K Cl along with a myriad of other elements which preform unique roles in the body. many the enzymatic reactions that keep us alive uses transition metals (the metals in the middle of the periodic table) for catalysis examples are Fe for oxygen transport by hemoglobin and Ni for fluid secretion and pH balance by Carbonic anhydrase The earth isn't alive. As for life on earth, there are some elements it could do without. Heck some are made in the lab and don't last more then a couple minutes

Please follow the links for some of the elements in the periodic table (link attached) and read the articles.
Many people do to determine which element is in a substance ex: me, scientists
The answer is a treatise with many volumes and is not possible on Wiki Answers; read a book of general chemistry.

- allowed rational ordering of chemical elements- predicted the properties of unknown elements- the chemical behavior of chemical elements can be predicted- the atomic radius can be predicted- the melting point can be predictedand more
The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
The sixth element of the periodic table is Carbon with an a symbol of C, an atomic number of 6 and an atomic mass of 12.0107carbon
Lots of the elements have few or no practical uses. Many of the artificial radioactive ones (e.g. Einsteinium) have no uses outside research. Others such as thallium are so toxic that they are only used in very specialized situations. You can use the link to an interactive periodic table to explore the uses of the elements. If you are looking for the answer to a specific question, be sure to be clear whether uses of the compounds of the element count or not.
