Title : Rather Be Chemistry
By : Chem Beatz
We have learned periodic table, a table of elements
There are metals and non-metals, and some are transitional
It has periods from one to seven, groups from one until eighteen.
They all have different reaction, have different properties
The gases fill the space moving to other place, strolling so casually
Halogens are the same although have different names high electronegativity
If you give a chance to explain it
Know all the types so you know how to use it
Know with all of your hearts you can ask me
When you are with me with you will love chemistry
When you go across the period the atomic radius decrease
There is a strong force of attraction effective nuclear charge increase
Going down the table’s group the atomic radius increase
Electron undergoes some repulsion nuclear charge decrease
Energy required to remove an electron, ionization energy.
The energy release when electron is added electron affinity
