Which of the following statements is correct and provides the best explanation when removing the first two electrons from calcium?

Energy is released when either electron comes off because calcium is a metal and not very electronegative.

It takes less energy to remove the second electron from calcium compared with the first because calcium wants to have eight electrons in its outer shell (and thus have a noble gas configuration.

It takes less energy to remove the first electron compared with the second because it is in a higher energy level than the second electron.

Electrons cannot be removed from calcium because it is a metal and only wants to gain electrons to become more stable.

It takes more energy to remove the second electron compared with the first because the nucleus binds the electrons more tightly as each electron is removed.

Interpretation Introduction

Interpretation:

The question specifically requires one provide the best possible explanation related to the removal of the first couple of electrons from calcium atoms.

Concept Introduction:

Each atom would like to achieve stable electronic configuration via removal of the electrons or acceptance of the electrons. Less electronegative (or electropositive) atoms would like to remove electrons while the electronegative atoms would like to accept the electrons to achieve noble gas configuration. Depending on the removal or acceptance of electrons atoms would either produce positive or negative ions.

Explanation

Reason for true statements:

Calcium atom has an atomic number of 12.It has twelve electrons and two electrons in the valence shell.In order to achieve stable electron configuration of the adjacent noble gases calcium can either remove two electrons (which gives [Ne] configuration) or gain six electrons to gain [Ar] configuration. Calcium is a metal and hence an atom with very low electronegativity (or highly electropositive) and hence would prefer removal of two valence electrons to gain [Ne] configuration and then become more stable.

Removal of electrons require energy since they are bound to the nucleus. These energies are known as ionization energies...
