Consider successive ionizations of the element Ca. Which ionization would you expect have the largest increase relative to the previous one?A) 2ndB) 3rdC) 4thD) 5thE) 6th

B) 3rd

Explanation:

The 3rd ionization energy represents the removal of electrons from a filled core shell.

The electron configuration of calcium is [Ar]4s^2. Hence after the removal of the second electron from the 4s^2 orbital, a lot of energy is required to remove an electron from the next completely filled core shell. This is the highest successive jump in ionization energy. The other options in the question deal with electrons found on the same shell.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
