Answer:
Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton
Step-by-step explanation:
Based on periodic trends, the atom that has a larger ionization energy than calcium are Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton.
Across the period, the ionization energy increases from left to right.
- Ionization energy is the energy required to remove the most loosely held electron within an atom.
- As you go from left to right, the ionization energy increases rapidly.
- The elements to the right of Ca will have a higher ionization energy compared to Ca.
