Question

Part H Use the electron configurations to explain the differences between your answers to Parts F and G.

Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer.

Choices:

S, 3, harder, right, 2, left, P, 5, Ca, 4, easier, Ga

According to your ranking, Ca and Ga would have the largest radius out of the five elements. This is because they are in period n = ___ .

Ga is smaller than Ca because radius increases as you move to the ___ across the period.

S is smaller than P and P is smaller than Si because as you move to the ___ across the period, radius decreases.

According to your ranking, the first ionization energy of Ga is smaller than the first ionization energy of Ca. This is because the element ___ loses the electron from the 4p orbital, which is shielded by the electrons in the ___ s orbital. The element ___ loses the electron from the filled ___ s orbital, which has added stability because it is a filled orbital.

According to your ranking, the first ionization energy of S is lower than the first ionization energy of P. This is because the element ___ has a half-filled ___ p orbital, which adds extra stability, thus making it ___ to remove the electron. The fourth electron in the 3p orbitals of the element ___ experiences added electron-electron repulsion because it must pair with another electron in the same 3p orbital, thus making it ___ to remove.
