Group 18 are the noble gases neon,argon,helium,krypton,xenon,radon

period tells you what row the elemt is in the group tells you what collum the elemt is in

metals are in the red, non metals are in blue,metalloids are in yellow. The noble gases are He, Ne,  Ar, kr, Xe, and Rn.-vylette.t

Henry Moseley found and measured a property linked to Periodic Table position. Hence atomic number became more meaningful and the three pairs of elements that seemed to be in the wrong order could be explained.

Lothar Meyer arranged the elements by atomic number.

Periodic table was invented by dmitri Mendeleev

The periodic table provides a useful framework for analyzing chemical behavior and is widely used in chemistry

the periodic table has nonmetals, metals, gases,etc. it helps us find the element that we need, using the atomic mass and the amount of protons,neutrons and electrons that it has. -vylette. t

The periodic table is a tabular arrangement of the chemical elements by increasing atomic number which displays the elements so that one may see trends in their properties.

# data[].attributes.body
the periodic table has rows and columns is is arranged by their atomic number it is divided by different parts it has metals  their is only 7 non metals noble gases are in the right the group is 1 too 18 and the columns are  1 thru 7

Most of the elements on the periodic table are metals. The alkaline metals, alkaline earths, basic metals and transition metals are all groups of metals.

elements with an atomic numbersplit up into metals non metals and metalloids

the periodic table is a table when symbols, atomics numbers, and are separted in rows and columns

the periodic table is a table that has rows of columns and chemical elements are put in order. and they have symbols that repersent certain chemicals

The periodic table is a tabular arrangement of the chemical elements ordered by the atomic number
The rows of the table are called periods, the columns are called groups for example:
Group 18 the noble gases
Group  17 are the halogens
Periods is a horizontal row  in the periodic table.
the periodic table is separated in metalls, non-metalls, and metalloids.
Metals are shiny, solid, ductile, malleable.Non-metals are brittle not malleable or ductile. And metalloids are economical important because because of their unique conductivity properties

only 90 elements occur in nature the rest of the elements are man made

a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

The periodic table show chemical elements , ordered by colums each one with atomic number , electron configuration and number of protons , this are divided by metals , non- metals and noble gases in the last column!

The table has chemecial elements that are separated in rows , columns and sections such as non metals and metals , each chemical element has a atomic number, mass and symbol it helps us better identify which element is which.
