An Exercise in Pattern Recognition

WARNING: This presentation may contain images and other intellectual content stolen
brazenly from the internet without the permission of the owners. It is meant for nonprofit use by Mr. Barnes’ current chemistry students only. Do not copy or distribute this
file. Its very existence may be illegal.
WARNING: Pedagogically, this lesson takes an awful lot of chances. It might have to
be scuttled for all but gifted classes . . . But then, again . . . Hmmm . . . .
. . . Inductively determine the sub-atomic
particle-based mathematical definitions of
atomic number, mass number, and electric
charge, after looking at the statistics for several
example atoms.
. . . Induce the laws of nature by looking at data.
“SWBAT = “Students will be able to”
NOTE TO CREATOR:
You need to make a proper worksheet for this activity.
It needs to include not only the grey boxes FITB side, in portrait
format, but also questions about how students determined the
mathematical definitions of atomic #, mass #, and charge.

If you already know the rules for atoms about protons, neutrons,
electrons, atomic number, mass number, and electric charge,
please don’t tell other people in your group what they are. It will
kill the learning experience for them. They need to exercise their
thinking muscles.
Look at your first atom and copy down its information in a neat,
tabular format. (Rows & columns – make a data table.)
Look at your Atom Rules Determination Activity worksheet and
see if you think you can make any educated guesses about what
goes in the boxes. (In other words, hypothesize.)
Pick another atom, copy down its stats, and decide whether or not
your guesses about what goes in the boxes are correct.
Repeat this cycle until you’ve seen so many atoms that you feel
very confident that you know what the rules about atoms are.
At some point during the period, your instructor will start asking
the audience what they think the rules are for atoms. Students
will be asked to explain why they believe what they believe, based
on the example atoms provided. If the instructor says an answer
is right, correct your worksheet answers if necessary.

In an atom’s symbol, mass number
is a left-hand superscript.
In an atom’s symbol, electric charge
is a right-hand superscript.
In an atom’s symbol, electric charge
is written # first, then sign (idk why!)
Atomic number = number of protons.
Atomic number determines element.
Mass number = protons + neutrons
Electric charge = protons - electrons

Neutrons have no electric
charge. (They’re neutral.)
Electrons have a -1
electric charge.
Protons and neutrons
have roughly equal
mass, but that of the
neutron is slightly larger.
Electrons have very little

protons and neutrons.
