Inside of batteries is where you’ll find me,
Just plug one in, and you will see.
My name’s Greek for “stone”, ironically
But, I’m the lightest element known to thee.
What is lithium

J.J. Thomson developed the "Plum-Pudding" model for the atom by using the results of Dalton's work AND by carefully using this property of matter
What is charge

Rows are called this because of the repeating patterns found in chemical reactivity among the elements.
What is periods

This subatomic particle is the only one found outside of the nucleus.
What is the electron

A chemical in the pool
You put it in often
Keeps it clean all summer long
As clear as the water.
What is chlorine

I’m named for the same man as an award.
Too much of me is a radiation hazard.
My look is unknown, but guessed at.
My atomic weight is 259, so I suppose I am fat.
What is nobelium

Elements in the modern periodic table are organized first by atomic number (# of protons) AND also by this property of matter (which protons AND neutrons both contain)
What is mass (atomic mass or weight)

Cr
What is chromium

These three categories are the most general way to organize elements by their properties. Most are on the left, a few in between, and the rest on the right.
What is metals, metalloids or semi-metals, and non-metals.

To park you must put me in the meter,
And you’ll need 5 of us to last more than a jiffy.
My neighbor used to be in coins like I am now,
But he has a proton more than me.
