In this lesson, you learned about the properties and location of metalloids. In this assignment, you will contrast the properties of metalloids with the properties of other groups of elements, and practice applying these properties to new situations to solve problems. Be sure to use the periodic table as you work on this assignment. Refer to the position of elements on the table to help you solve the problems.

Explanation:

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
