Periodic Table

Hi! Tomorrow I have a science test and I thought it would help me to write a small poem. This makes it easier to study. To me it works as a study guide, I hope it will help you too. Please enjoy.

Periodic Table Poem

The father of the periodic table is Mendeleev,

He ordered the table by atomic mass, so this title he received,

Next Moseley changed the table to go by atomic number,

So it is different from the way things were,

The particles can be arranged in a Bohr Model,

The 4^th ring can hold 32e-, 3^rd ring 18e-, 2^nd ring 8e’, and 1^st 2e- because it’s very small,

In the periodic table most metals are on the left and most non-metals are to the right,

And metalloids are touching the stair step which is always in sight,

Hydrogen is the only non-metal on the metal side,

It is on the very top, it does not hide,

The columns up and down are known as groups or family,

Rows go across and called periods as everyone can see,

Most metals are solids and most non-metals are gas,

And gases that do not form compounds are known as “Noble Gas”,

The electron cloud surrounds the nucleus which is the middle,

And the electron cloud’s mass is very little,

Atomic number, protons, and electrons are always the same,

This way you don’t need to do math, it is not a pain,

Atomic mass – atomic number = the number of neutrons,

This equation is never wrong,

Figure out the valence to find out the charge,

By doing a Bohr model it doesn’t have to be large.
