Organization of Matter and Chemical Interactions
Atoms are the basic building blocks of ordinary elements. Compounds are substances composed of two or more elements. Chemical formulas can be used to describe compounds. The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns. The element position on the periodic table can also be used to predict the type of bonding that most commonly occurs between the elements.
Students will demonstrate an understanding of the proper use of the periodic table to predict and identify elemental properties and how elements interact.
