Physical Science Unit 1 Day 3 Part 2

Learning Objective: Students will learn about patterns and trends on the periodic table by coloring and labeling the periodic table and will describe in writing their observations using technical language electronegativity, ionization energy, atomic radius, valence electrons, periods, groups, families.



Questions:

1. When atom size increases, electronegativity decreases--why do you think this is? (brain)
2. When valence electrons get closer to 8, electronegativity increases--why do you think this is? (brain)
3. Which statements are true about the periodic table?

Write only the correct answers in your notes. There should be 3 correct.
	A. Each box on the table represents one element. B. Elements in the same row of the periodic table have the same number of electrons. C. There are two different ways to number the groups of the periodic table. D. The periodic table is organized by atomic number.

Exit Ticket for Day 3: Describe the patterns and trends in the periodic table using the following sentence starters:

The first pattern I notice is ___________________, this is probably like this because....

The second pattern I notice is _______________________ . This is probably because...
