Just like passengers getting on a bus, electrons orbit the nuclei of atoms in particular patterns. You will discover these patterns (and how electrons sometimes act like passengers boarding a bus) with the Electron Configuration Gizmo. To begin, check that Lithium is selected on the PERIODIC TABLE tab

1.) The atomic number is equal to the number of protons in an atom.
How many protons are in a lithium atom?

2.) A neutral atom has the same number of electrons and protons.
How many electrons are in a neutral atom?
