Each individual square in the Periodic Table represents one element. It gives the chemical symbol for the element. The number for the element, which is the number of protons. It gives the average atomic weight. The atomic weight is roughly the weigh of the protons and the neutrons. For example: Uranium, element number 92, has the symbol U. It has 92 protons. It comes in 3 isotopes or different forms but with the same chemical properties. It comes as U 238, U 234, and U 235. That means Uranium 238 has 92 protons and 148 neutrons. Depending on the periodic table, it may also have other information.
it represents an element, having an atomic number and name to describe it.
It's more the one option you didn't ask: neither. They're elements. The data on the table is for an individual atom; the element may exist as individual atoms, or as molecules, or as metals.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
There is no Pg on the periodic table.

Coal is not on the periodic table.
On the periodic table there are squares. Each square corresponds to one element.
The shaded squares on the left are metals. they are placed in group-1 and 2.
Periodic table comprises of elements. These are arranged in groups and periods.
In the periodic table only the chemical elements appear; but tables for isotopes also exist.
it stands for an element. different squares represent different elements

A Periodic table The Periodic Table of the Elements.
The individual blocks are the individual elements, ie: Hydrogen, Helium, Lithium etc etc.
Following are mentioned in the squares:1. Symbol of element2. Atomic number
atomic number
Only individual elements have a place on the periodic table, but glucose is composed of three different elements: carbon, hydrogen, and oxygen, so it doesn't belong anywhere on the table.
Every individual block on the periodic table ... all hundred-and-some of them ... represents an atom, with a structure different from all the other ones.
