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 released when an atom gains an electron.
The energy required to remove an electron from a gaseous atom.
The energy stored within an atom's nucleus.
The energy required to break a chemical bond.
2. Which of the following elements would have the highest first ionization energy?
Lithium (Li)
Sodium (Na)
Fluorine (F)
Chlorine (Cl)
1. Ionization energy generally across a period and down a group on the periodic table.
2. The ionization energy is always greater than the first ionization energy.
3. The shielding effect the effective nuclear charge, making it to remove an electron.
1. Explain why the first ionization energy of noble gases is very high.
2. Describe the trend in ionization energy as you move from left to right across a period in the periodic table. What factors contribute to this trend?
1. Removing an electron from a cation requires less energy than removing it from a neutral atom.
True
False
2. Larger atomic radius generally leads to higher ionization energy.
True
False
Observe the diagram of an atomic structure below and answer the question.
1. Based on your understanding of ionization energy, identify which electron (if any are depicted as removable) would require the least energy to remove from this atom. Justify your answer.
