Quantum Mechanical Model of the Atom: Organization of the e-

Where are electrons?

Where are the electrons?

There's no certainty, but there is probability. The "cloud" indicates probability - where it's more heavily shaded, there's more probability and where it's lighter in shading, there's less probability that the e- is at that location.

How many electrons in each orbital?

Each orbital can be empty, have 1, or a maximum of 2 electrons in it

Use the periodic table to help you figure out how many sublevels, orbitals and number of e- are in each energy level. The next slide sums it up...

Energy

Energy increases as you move up (i.e. 2nd E level is higher than first) as well as in sublevel (s is lowest, then p, then d, then f)
