How does the atomic radius change as you move from top to bottom within a group in the periodic table?

• Increases

• Decreases

• Fluctuates

• Remains constant

What factors influence the ionization energy of an atom?

• Temperature, pressure, and volume of the atom

• Atomic mass, atomic number, and electron configuration

• Number of protons in the nucleus, number of neutrons in the atom, and number of electrons in the outer shell

• Nuclear charge, distance of the outermost electron from the nucleus, and shielding effect of inner electrons

Why does electron affinity generally become more negative as you move from left to right across a period in the periodic table?

• Electron affinity is not affected by the position in the periodic table

• Stronger nuclear charge attracts electrons more strongly

• Electron affinity decreases as you move from left to right

• Weaker nuclear charge repels electrons more strongly

Explain the trend of electronegativity as you move from top to bottom within a group in the periodic table.

• Electronegativity decreases

• Electronegativity increases

• Electronegativity remains constant

• Electronegativity fluctuates

What is the relationship between the number of protons and the ionization energy of an atom?

• The ionization energy of an atom is inversely related to the number of protons.

• The ionization energy of an atom is directly related to the number of protons.

• The ionization energy of an atom is only related to the number of neutrons.

• The number of protons has no effect on the ionization energy of an atom.
