Coulombic Attraction Practice

If the number of energy level rings 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.
