Do Now
Objective: Students will identify and make connections about periodic table patterns and trends by coloring and labeling a periodic table and using the words electronegativity, ionization energy, atomic radius, valence electrons, reactivity.

Questions:
1) What elements are the most reactive? Why?
2) What property do elements in the same group have in common?
3) What elements are least reactive? Why?

Exit Ticket:
What patterns or trends are in the periodic table? Write a perfect 3 sentence paragraph using the following sentence stem "The periodic table shows a pattern because..." and at least 1 green word from the objective. Be sure to have 1 of your classmates read and evaluate what you wrote.
