How does the atomic radius change as you move down a group in the periodic table?

• It decreases because the number of energy levels increases

• It increases because the number of energy levels increases

• It remains constant because the number of protons changes

• It decreases because the atomic number increases

What trend in atomic radius occurs as you move from left to right across a period in the periodic table?

• The atomic radius increases because the nuclear charge decreases

• The atomic radius decreases because the nuclear charge increases

• The atomic radius remains constant because the number of energy levels remains the same

• The atomic radius increases because the number of neutrons increases

Why does Fluorine (F) have a smaller atomic radius than Lithium (Li)?

• Because Fluorine has fewer protons than Lithium

• Because Fluorine has more energy levels than Lithium

• Because Fluorine has a higher nuclear charge, pulling electrons closer

• Because Lithium is a gas at room temperature
