Question 3 Compounds composed of only TWO elements are called what? Answer: Binary

Question 4 When you mix two liquids together and a solid is formed, what is this solid called? Answer: Precipitate

Question 5 What three main categories can the elements on the periodic table be divided into? Answer: Metals, nonmetals, metalloids
