Periodic Trends

When you move left across the table, the radius ____. When you move down the table, the radius ____.

• Increases, Decreases
• Decreases, Increases
• Increases, Increases
• Decreases, Decreases

As you move across the periodic table atoms tend to get smaller because, ______________.
