Is it the same as an atomic number? I'm confused

I know what an atomic number is, what its relationship with the atomic structure is and all, its just that I have a lab that asks me to graph the period number as a function of density...oh hahaha. jk...it says period number

The periodic number is the same as an atomic number. The atomic number is the number located above the atomic symbol and thus numbers where it is located on the periodic table. For example, the symbol for helium is He and the atomic number is 2. if you look at the periodic table you will find helium by looking for He or the number 2.

The periodic # is the number of protons. This defines the element ( such as gold, or neon). The atomic number has protons and neutrons. The number of neutrons doesn't change the element, but makes it "radioactive" or not. The other numbers, are the electrons, which determine how an element will "react" with another to form a compound.

It's because the elements are arranged in 'periods', ie. repeating sets. The horizontal rows are periods. The elements in a period share similar properties, therefore they are grouped together. Really, the only reason it is caleld the "periodic" table is because of it's way of organization, that puts the elements together. Rather, if in the rows the elements shared no properties, it would not be organized as such and would not be the periodic table.

im pretty sure its the # given to the specific element/chemical/gas on the periodic table, not an atomic #. but you might want to google it, im not exactley sure.

It was periodically updated.

It is a place in the chart of Chemical Elements.
