longer |
|

9.9 x 10^-18 J |
|
|
Rank the types of electromagnetic radiation from highest energy to lowest energy? |
gamma, X-ray, ultraviolet, visible, infrared, microwaves, radio |
|

Hund's Rule
|
|
|
What type or relationship exists between wavelength and frequency: direct or inverse? |
inverse, because when one goes up the other must decrease OR if one decreases the other must increase. |

What is wrong with the electron configuration pictured?
|
The 3p orbital should fill with 6 electrons before beginning to fill the 4s orbital. |
