The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
Today (June 2013) the periodic table contain 118 chemical elements, natural or artificial.
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
In the periodic table, N2 stands for nitrogen gas. Nitrogen gas consists of nitrogen molecules made up of two nitrogen atoms bonded together.
The columns in the periodic table are called groups or families. These columns contain elements with similar chemical properties due to their shared number of valence electrons.
All of the metals on the periodic table are on the left side. Your periodic table probably has what looks like a broken diagonal line running around the middle. Everything to the left of this line (except hydrogen) is a metal.
The periodic table contain all the chemical elements.
Periodic table contain only chemical elements.
