Physical Science Unit 1 Day 4

Language Objective: Students will learn about communicating ideas in writing and will analyze information learned in unit 1 about the periodic table using technical and academic vocabulary (patterns, trends, properties, valence electrons, reactivity, electronegativity, atomic radius, protons, neutrons, energy levels) and Claim-Evidence-Reasoning graphic organizer.



Questions:

1. What did we do in unit to learn about the patterns and properties of the periodic table?
2. What did you learn from unit 1 about the periodic table? Atoms and properties?

Why do elements in the same group have a similar reactivity?
	A. The elements of a group all have the same number of electron shells. B. The elements are all the same color. C. The elements of a group have the same number of valence electrons. D. The elements all have the same atomic mass.
