i don't really know this but as you can see they let me write it so i think ... the element are the solids gas and metals in the table that have been spilt up into groups

Periods are types of elements.
118 elements are in the periodic table of elements; some of them are still unnamed (January 2013).
In some periodic tables
There are no compounds in the periodic table, only elements. There are between 114 and 117 elements (some are awaiting confirmation and a couple remain unnamed).
These chemical elements are called transition metals.
The elements are arranged in the increasing order of their atomic number and repeating properties.
112 elements have been named and additional 6 elements have been tentatively proposed.
Metals are located on left side in periodic table.Eg-group 1,2 elements
Periodic tables are important in most scientific classes because they help understand similarity of properties and reactions of elements.
Periodic tables are important in Chemistry classes because they help understand more about protons, electrons, and neutrons of various elements.
Because the elements that have similar properties are arranged in groups - or 'periods'.
