Which of the Following Statements Is Correct and Provides the Best

question 1

Multiple Choice

Which of the following statements is correct and provides the best explanation for what happens when the first two electrons are removed from calcium?

• A) Energy is released when either electron comes off since calcium is a metal and not very electronegative.
• B) It takes less energy to remove the second electron from calcium as compared to the first because calcium wants to have eight electrons in its outer shell (and thus have a noble gas configuration).
• C) It takes less energy to remove the first electron as compared to the second because it is in a higher energy level than the second electron.
• D) It takes more energy to remove the second electron as compared to the first because the nucleus binds the electrons more tightly as each electron is removed.
• E) Electrons cannot be removed from calcium since it is a metal and only wants to gain electrons to become more stable.
