About Orbitals

Please watch this video for homework tonight.  It is a little advanced so try not to feel overwhelmed.  Electron orbitals are abstract and therefore a bit confusing!

The following questions should help guide your learning.

1. Which scientist devised the concept of energy levels and orbitals?
2. What subatomic particle exists in orbitals?
3. Are these orbitals 2-Dimensional or 3-Dimensional?
4. Are they well defined paths?
5. What is energy?
6. What makes an electron “excited?”
7. Each period in the periodic table will have ________ energy shell
8. How many elements are in the first period?  What are they? How many protons & electrons do they each have?

Just to get us started...

Below is a great website that provides a basic overview of the concepts we will be learning about in this next section.  Make sure you look at the section called "Atomic Basics".
