Plastics are made through organic chemistry (the study of carbon compounds).
ALKENES are used to make plastics.
Plastics consist of many repeated monomers (small molecules).
The basic elements that make up most plastics are Carbon,Hydrogen,Oxigen,Nitrogen,Chlorine and Sulfur.(good job dumbo you spelled oxYgen wrong)
There are 32 elements in the 6th period of the periodic table.

H2O isn't a single element, which is what the periodic table Most things are made of compounds of these elements. . It is comprised of 2 hydrogen atoms (H, on the periodic table) and oxygen (O, on the periodic table).
Some elements in the periodic table have a nucleus that is surrounded by a cloud of electrons with a negative charge. This is one sentence using nucleus and periodic table.
There are more metals than nonmetals on the periodic table. There are 18 nonmetals, compared to 117 known elements.
118 elements.
To make study of elements easier.To classify elements.
No they did not.
The answer is Group 17 Halogens.
There are 32 elements in the 6th period of the periodic table.
The order of the periodic table is made according to the atomic weights of the elements. The number of protons and neutrons in the nucleus make the atomic weight. Protons make the elements in order of the periodic table.
including "unknown elements" there are 59 elements in half of the periodic table, not including them there is 55.5 Added: 92 natural elements/2 = 46 natural elements make up 1/2 periodic table.

NaI is the compound named sodium iodide made of the elements sodium (Na) and iodine (I). You will find the elements themselves on the periodic table, not the compounds they make.
He is the founder of the periodic table. He arranged the elements according to the atomic masses. Few changes are made in his periodic table to make the modern periodic table.
It is called the key of life because all the elements or compounds of the elements of on the periodic table make up the world.
182 I don't think there are compounds in the periodic table. As far as I know the periodic table contains only elements, compounds are formed by ionic/covalent bonding which is another story already. http://www.webelements.com/
