1.7 - Periodic Trends(AP)

Why is there a large jump in ionization energy for the 11th electron?

• The 11th electron is closer to the nucleus.

• The 11th electron is in a new energy level.

• The 11th electron is more tightly bound to the nucleus.

• The 11th electron is in a higher energy state.

What remains unchanged as electrons are being lost from an atom?

• Number of electrons

• Number of protons and neutrons

• Energy levels

• Atomic mass

What is the electron count change during the 5th ionization energy?

• 8 to 7

• 7 to 6

• 6 to 5

• 5 to 4

What happens to the electron in the 10th ionization energy?

• It is removed from the 1st shell.

• It is removed from the 2nd shell.

• It is added to the 1st shell.

• It is added to the 2nd shell.

What is the trend for atomic radius as you move from left to right across a period?

• It increases

• It decreases

• It remains constant

• It doubles

Which element is in the second column of the periodic table?

• Boron

• Beryllium

• Lithium

• Sodium

What is the relationship between electron movement and atomic radius?

• Electrons move away, increasing atomic radius

• Electrons move closer, decreasing atomic radius

• Electrons remain stationary, no change in atomic radius

• Electrons move randomly, fluctuating atomic radius

What remains the same in a cation compared to its parent atom?

• Number of electrons.

• Number of protons.

• Atomic radius.

• Number of electron shells.

How does the number of protons affect the size of a cation?

• More protons increase the size.

• Fewer protons decrease the size.

• The number of protons does not affect the size.

• More protons decrease the size.

What is the effect of more protons on electron affinity?

• It decreases electron affinity.

• It increases electron affinity.

• It has no effect on electron affinity.

• It makes electron affinity zero.
