Description

Information relating atoms and how they combine to form chemical bonds is presented in this unit. Bonding begins with the movement of subatomic particles called electrons. Electrical charges are generated by the transfer of electrons between objects. An excess of electrons imparts a negative charge, whereas a deficiency causes an object to have a positive charge. Objects with like charges repel each other, whereas oppositely charged objects attract each other. Chemical bonds form molecules and compounds that make up all states of matter.
