Atomic Size Trends in the Periodic Table

The video tutorial explains how to determine which atom is larger between fluorine and magnesium by examining trends in atomic size on the periodic table. It highlights that atomic size decreases across a period and increases down a group. By comparing the positions of fluorine and magnesium, it concludes that magnesium is larger due to its position lower in its group and further left in its period.

What is the general trend for atomic size as you move across a period in the periodic table?

• Atoms get larger

• Atoms get smaller

• Atoms remain the same size

• Atoms become more metallic

How does atomic size change as you move down a group in the periodic table?

• Atoms remain the same size

• Atoms get larger

• Atoms become less metallic

• Atoms get smaller

Which atom is larger, fluorine or magnesium, based on their positions on the periodic table?

• It cannot be determined

• Fluorine

• They are the same size

• Magnesium

Why is magnesium larger than fluorine?

• Magnesium is higher in its group

• Magnesium is lower in its group

• Fluorine is to the left of magnesium

• Fluorine is lower in its group

What is the relationship between atomic radius and position on the periodic table?

• Atoms on the right are larger

• Atoms at the bottom are larger

• Atoms at the bottom are smaller

• Atoms at the top are larger

Which of the following statements is true about the atomic size trend on the periodic table?

• Atoms get smaller as you move down

• Atoms get larger as you move to the right

• Atoms get larger as you move down

• Atoms remain the same size across periods
