The vertical "groups" group elements by chemical properties
the horizontal "periods" group elements by the number of energy levels
On the periodic table metals are listed on the left side.
The elements are listed in the order of how many atoms they have. For example, hydrogen is the first element on the periodic table. Hydrogen is the smallest element, and has one atom.
The information like element symbol and its atomic number are listed on a element in periodic table.

He listed the elements in his periodic table in groups in which he saw patterns. He left gaps where he thought elements had not yet discovered. Hope this helps :p
The halogens, listed in column 17 of a wide form periodic table.
- the periodic table is organized in periods and groups- chemical elements are listed in the order of the atomic number- the periodic table obey the law of periodicity

The elements that are listed in vertical columns all share specific aspects. These aspects include having the same number of valence electrons and having similar chemical properties.
Uranium and arsenic are listed in the periodic table because they are elements.
like as in the periodic table of how it is listed.

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.
