The amount of energy required to remove a valence electron is called

• Electronegativity
• Ionization energy
• Reactivity
• Atomic radius

How likely an atom is to change its number of electrons and form an ion is called

• Electronegativity
• Ionization energy
• Reactivity
• Atomic radius

Which of the following factors contributes to the trend for ionization energy as you move left to right across a row?

• Ionization energy decreases as attraction for electrons increases
• Ionization energy decreases as the size of the atom increases
• Ionization energy increases as the attraction for electrons increases
• Ionization energy increases as the size of the atom increases

Which is the best reason for the trend in atomic radius as you move down a column?

• The number of energy levels/electron layers increase
• The atoms get closer to having a full outer shell
• The attractive force of the nucleus increases
• The number of neutrons increase

What causes the trend for electronegativity as you move down a column?

• Electronegativity decreases and the number of protons increases
• Electronegativity decreases as electrons get further away from the nucleus
• Electronegativity increases as the number of protons increases
• Electronegativity does not change as you go down a column
