dalton's 6 postulates are- 1. all matter is made up of tiny particles called atoms 2.atoms are indivisible particles thtical elemat cannot be divided 3.atoms of identical elements are equal in mass and chemical properties. 4.atoms of different elements have different masses and chemical properties. 5.atoms divide in the ratio of small whno.ole
Meatals: 88 Semimeatals: 6 Nonmeatals: 18 Add: Groups 1 and 18 contain 7 elements. Groups 2, 13-16 contain 6 elements. Groups 3-12 contain 4 elements. Some periodic tables do not include all of the elements 113-118 as only a few atoms of each have been observed in the laboratory.

He made the first ever periodic table, that was the revolutionary thing Mendeleev made.-----01/6/2012Mendeleev's discovery about elements were so revolutionary because he left gaps for undiscovered elements. He predicted the elements properties to get the empty spaces that would later be proven true (the prediction of the other undiscovered elements) in 1875 by a scientist.

There is a very specific order called a Periodic Table. All elements are arranged based on the number of protons. Hydrogen is number 1, it has 1 proton. Carbon is number 6, it has 6 protons. These values are called the Atomic Number. The atomic number of the elements increases accross the Table from left to right. In addition the table groups the elements into types (Inert Gases, metals etc and shows elements with similar properties in columns of increasing Atomic Number (top to bottom). As a bonus the Table generally contains information on Atomic Weights, completed orbitals, isotopes and similar. The elements may also be listed alphabetically by name (Helium, Iron, Silver etc.) or symbol (He, Fe, Ag, etc.)
112 elements have been named and additional 6 elements have been tentatively proposed.
There are a total of 118 elements known to exist on the periodic table.
He is famous for playing Baseball and Basketball, although, he was more better at basketball. He came up with the famous dunk called Air Jordan, was named the 1991 NBA MVP, and has won 6 NBA titles.
The higher elements are forged in the center of stars. Most stars can create up to about element 6-8 on the periodic table, but any elements higher than that require a super nova.
IUPAC
there are 32 elements in period 6.
The 6 elements of culture are; communication, technology, social organizations, geography, beliefs and customs, famous people and places.
8 sets of 6 elements would have 96 elements (8X6=96)
There are 6 elements; 1,2,3,4,5,&6.
