Bonding

An LED with an electrical current running through it, also glowing.

A side experiment my classmate and I did to see if poking the end of the LED, and the end of the resistor into a orange would still allow the LED to glow. (It did)

LEARNING REFLECTION

In this section we learned mainly about covalent and ionic bonds. We learned that the main factor in the difference in covalent and ionic bonds is binding energy. If there is an unequal BE, then the bond will be ionic, if the BE is equal then the bond will be covalent. Ionic bonds are more of an attraction than a bond, and covalent bonds are full bonds. We also learned how to draw Lewis Structures, and skeletal structures. We learned that when drawing the skeletal structures, carbons are represented by kinks in the line, and hydrogens are not written in, but simply assumed. I'm still a bit shaky on mole conversions, but I'm also prone to small mathematical errors during tests so I know that's part of it. I'm going to practice mole conversions more.
