Exploring Periodic Table Trends and Coulomb's Law

What happens to the atomic diameter as you move across the periodic table?

• It gets larger.

• It gets smaller.

• It remains the same.

• It fluctuates randomly.

According to Coulomb's Law, what happens when opposite charges are near each other?

• They remain neutral.

• They attract each other.

• They cancel each other out.

• They repel each other.

What is the effect of having two protons in the nucleus on the atomic size?

• The atom gets larger.

• The atom remains the same size.

• The atom becomes unstable.

• The atom gets smaller.

Why does the atomic diameter get smaller as you move across the periodic table?

• Because the number of protons increases, pulling electrons closer.

• Because the number of electrons decreases.

• Because the nucleus gets larger.

• Because the atomic mass decreases.

How does the atomic size change as you go down the periodic table?

• It gets larger.

• It fluctuates.

• It gets smaller.

• It remains the same.

What is the main reason for the increase in atomic size down the periodic table?

• Decrease in neutron number.

• Decrease in electron number.

• Increase in proton number.

• Increase in electron shielding.

What is electron shielding?

• The process of electrons being pulled closer to the nucleus.

• The repulsion between electrons in different shells.

• The attraction between protons and electrons.

• The force that keeps electrons in orbit.

How does electron shielding affect the outermost electron in an atom?

• It has no effect on the electron.

• It pushes the electron further from the nucleus.

• It pulls the electron closer to the nucleus.

• It makes the electron neutral.

What is the relationship between the number of electron shells and atomic size?

• The number of shells does not affect atomic size.

• More shells result in a larger atomic size.

• Fewer shells result in a larger atomic size.

• More shells result in a smaller atomic size.
