Questions & Step-by-Step Solutions
What is the first ionization energy of magnesium (Mg) in kJ/mol?
Step 1: Understand what ionization energy means. It is the energy required to remove one electron from an atom.
Step 2: Identify the element in question, which is magnesium (Mg).
Step 3: Look up the first ionization energy value for magnesium in a reliable source, such as a chemistry textbook or database.
Step 4: Find that the first ionization energy of magnesium is approximately 738 kJ/mol.
Step 5: Confirm that this value is for the first ionization, meaning it is the energy needed to remove the first electron from a neutral magnesium atom.
