To Tend to Trend

Trendy Elements (Teresa and Claire)
Evanston Township High School, Evanston, IL

We are sophmores at Evanston Township High School and think Chemistry is a lot of fun. We wrote this song about Periodic Trends, because we thought it was one of the most interesting and useful concepts that we learned this year.

Period Trends help you know
Best broken down into groups
Or families
Useful in bonding of molecules

Atomic size increases down a group
Because electrons are added further from the nucleus
There's less attraction
Not to mention size decreases across a period

Atomic radii increases as you go down and left
Because it follows suit with size
And that's no lie

Let's converse about noble gases
All colorless at room temperature
Single atoms rarely react
With anything in the world

Alkali metals have a plus one charge
Alkaline earth metals are right next door
With a plus two charge
And it continues 'til the end
The oxidation trend

Atomic density increases right to left
Making metals be more dense
Than any non-metal
