This round we learn about Covalent Bonding and Ionic Bonding. As I have learned the Covalent Bonding is between two same atoms shared their electron to complete each other and stay stable. Ionic Bonding is between two different atoms, one of them give away their electrons to the other atom to both complete and stay stable. Our teacher also introduces us to chemical reaction at the end of the round. As I have learned chemical reaction is the result of two different molecules bond or hit each other.
