Here are questions to answer from Bozeman Bond Length and Bond Energy Video.
1) What forces determine how far away two atoms are to each other?
2) What property from the Periodic Table trends helps to predict this?
3) Is energy needed (+ΔH) or released (-ΔH) when a chemical bond is "Formed"?
4) Is energy needed (+ΔH) or released (-ΔH) when a chemical bond is "BROKEN"?
5) Align the following types of bonds from HIGHEST Bond Energy to LOWEST Bond Energy; Single bond (SB), Double bond (DB), Triple bond (TB)?
6) Align the following types of bonds from Longest Bond Length to Shortest Bond Length; Single bond (SB), Double bond (DB), Triple bond (TB)?
7) For example, a single bond between 2 different sets of elements will have different bond energy (and bond lengths). What causes the differences and what Periodic Table property can predict it?
