An Overview of Atom's First Chemistry

You may have been handed a textbook, curriculum, or nothing. They said, “You have a science background, right? We need you to teach chemistry”. So, you taught it.

Then, you came across some person who asked you how you taught or how you felt about atoms first versus traditional chemistry. And you sidetracked the question until you could get on Google and stumble on this article.
​
So here is the low down on atoms first.

It Starts Similar to Traditional

Both the traditional and atoms first approach to teaching begin by teaching some form of measurement, SI units, classification of mater, and significant figures depending on state standards. The last thing taught with both approaches is elements and atoms. Usually, some discussion of protons, neutrons, and electrons happens.

Diverges after Protons, Neutrons, and Electrons

The atoms first approach believes at this point we’ve talked about protons, neutrons, and electrons, so why not take this opportunity to dive into the secret structure of the atom.
​
Depending on your state standards this may include Lewis dot structures, beta decay, alpha decay, and other nuclear chemistry topics. It may also include quantum numbers and electron configuration.

Begins Periodic Table

After covering the miniscule details of the behavior of the electrons, the atoms first approach goes on to teach the layout of the periodic table, ion formation, naming chemical compounds, writing chemical formulas, balancing chemical equations, and so on.

It boils down to tackling the unseen, deep chemistry earlier rather than later.

​Atoms Come First

​So, atoms come first in the atoms first approach. The point is to teach the minute intricacies of the atom before you teach even the periodic table.

In short, you dive deeeeep into chemistry going all the way into the secrets of the atom then you go back to surface level topics like the periodic table and how elements combine. Then the topics just keep building like traditional chemistry.
​
My question to you is, “Is it more important for your high school educated student to go into the workforce knowing how to write an electron configuration or to know what solvents would work best to get a stain out of their shirt?”

    Hi! I'm CoScine. I write chemistry worksheets for visual learners. They are fun, easy to follow, and most of them are quick to grade. Since I started my teaching career at the college level, these are just simple chemistry. These worksheets are hard core science.
