Electron Configuration Activity
Cut and sort the 18 facts about electron configuration into two categories: True and False. Once you have identified the
FALSE statements, rewrite them as TRUE statements. Beware- there are not always an equal amount of statements in each
category. Take it a step further! Sort the statements into various categories and defend your categories. (In other words,
explain why you sorted them that way!)
The s orbital exists in all energy levels.
Electrons spin in the same direction
within an orbital.
The p orbital exists in energy level 3
and up.
Atomic orbitals are regions around the
nucleus where the neutrons can be
found.
The d orbital exists in energy level 3
and up.
Electron configuration explains how
the electrons are arranged around the
nucleus.
Each energy level holds 2 s orbitals.
The current electron model is the Bohr
model.
4 p orbitals can exist in energy level 2.
The correct electron configuration for
Na is 1s22s22p62s2
The d orbital is a sphere.
Periods on the periodic table tell you
the number of orbitals that exist for a
given element.
One orbital can hold 6 electrons.
Helium's electron configuration is
1s12p1.
"Quantum number" refers to the
number of valence electron.
The first energy level can hold 6
electrons.
The second energy level can hold 8
electrons.
Protons and electrons can be found in
the nucleus of an atom.
