Today’s Objectives...
• Atoms and sub-atomic particles

Atoms
• Smallest unit of matter• Composed of (sub-atomic particles)• Similar atoms make elements

Atomic number and mass• Atomic number is the number of protons
• The atomic mass is the approximate mass of the sub-atomic particles

Investigating Elements
• You’ll be put into a break out room with a group and be assigned an element.
• Use the dynamic periodic table to find out some cool info on your element. (3-4 things, nothing too technical)
• Draw a basic atom on the board with 4 protons, 4 neutrons, and 4 electrons.
