Content Standard 1:
Structure and Properties of Matter

Objectives:

2. Atoms interact with one another by transferring or sharing outer electrons that are farthest from the nucleus. These outer electrons govern the chemical properties of the element.

• Atoms can react to produce new substances. The formation of molecules results when atoms give, take, or share electrons.
