Which of the following elements has the highest first ionization energy?

Which of the following elements has the highest first ionization energy?

Correct Answer: Carbon

Step 1: Understand what ionization energy is. It is the energy required to remove the outermost electron from an atom.
Step 2: Know that elements in the same group (column) of the periodic table have similar properties, including ionization energy.
Step 3: Recognize that ionization energy generally increases as you move from left to right across a period (row) in the periodic table.
Step 4: Compare the elements given in the question. Look at their positions in the periodic table.
Step 5: Identify that carbon (C) is located in group 14 and has a higher ionization energy compared to elements in groups 1 and 2.
Step 6: Conclude that carbon has the highest first ionization energy among the elements listed.
