Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. What is ionization energy?
The energy required to add an electron to an atom.
The energy released when an electron is removed from an atom.
The energy required to remove an electron from a gaseous atom.
The energy stored within an atom's nucleus.
2. Which of the following elements would have the highest first ionization energy?
Lithium (Li)
Fluorine (F)
Sodium (Na)
Potassium (K)
1. Ionization energy generally across a period and down a group in the periodic table.
2. The an atom's radius, the its ionization energy.
3. The removal of a second electron from an atom requires energy than the removal of the first electron.
1. Helium has a lower first ionization energy than hydrogen.
True
False
2. Shielding effect decreases the effective nuclear charge experienced by valence electrons.
True
False
1. Explain why ionization energy generally increases across a period.
2. Describe the trend of ionization energy down a group in the periodic table and provide a reason for this trend.
Use the words below to complete the sentences.
1. As you move from left to right across a period, the generally , leading to a higher ionization energy.
2. Down a group, the increases, which contributes to a ionization energy.
