As the distance between protons and electrons increases, the force of attraction

• remains the same
• increases
• decreases
• is not affected

As you move from the smallest atom to the largest atom in Model 2, the attractive force between the valence electrons and the nucleus

• remains the same
• increases
• decreases
• is not affected

If distance remains the same, as the number of protons increases, the force of attraction

• remains the same
• increases
• decreases
• is divided by 1/2

What are the two variables that affect Coulombic Attraction?

• Distance  and number of protons
• Number of neutrons and number of protons
• Number of neutrons and number of electrons
• solids or liquids

If distance remains the same, as the number of protons increases, the force of attraction

• remains the same
• increases
• decreases
• is divided by 1/2

What is the trend in Coulombic attraction moving from left to right across a period?

• Coulombic attraction increases moving from left to right across a period.

• Coulombic attraction decreases moving from left to right across a period.

• No trend can be observed.

• The trend depends upon which period is being observed.
