Periodic Table Trends Exploration

What happens to the atomic radius as you move from left to right across a period?

• It increases.

• It decreases.

• It remains the same.

• It fluctuates.

Why does the atomic radius increase as you move down a group?

• The nucleus gets smaller.

• Electrons are lost.

• More energy levels are added.

• More protons are added.

What is the trend of ionic radius as you move from top to bottom in a group?

• It increases.

• It decreases.

• It fluctuates.

• It remains the same.

How does losing electrons affect the size of a metal ion?

• It gets larger.

• It fluctuates.

• It gets smaller.

• It remains the same.

What is ionization energy?

• Energy required to add an electron.

• Energy required to remove an electron.

• Energy required to form a bond.

• Energy required to split an atom.

Which element requires the most energy to remove an electron?

• Lithium

• Neon

• Fluorine

• Rubidium

What does electronegativity measure?

• The size of an atom.

• The ability to lose electrons.

• The ability to attract electrons.

• The number of protons.

Which element has the highest electronegativity?

• Lithium

• Neon

• Rubidium

• Fluorine

Why is fluorine highly electronegative?

• It has one valence electron.

• It needs one more electron to complete its valence shell.

• It has a full valence shell.

• It has a large atomic radius.

Why is the ionization energy of lithium lower than that of fluorine?

• Lithium has more electrons.

• Lithium has fewer protons.

• Lithium only needs to lose one electron.

• Lithium has a larger atomic radius.
