Explain the large increase in ionization energy needed to remove the third electron from beryllium compared with that needed for the second electron.
Removal of the third electron requires more energy because it must be removed from a 2+ beryllium ion, which has a(n) _____ ( Stable or Unstable) electron configuration, the same configuration as .
Homework Answers
Beryllium Be
Atomic Number - 4
electronic Configuration - 1S2 2S2
Position in periodic Table - Group no. 2 and Period 2
No. of electron in outer most shell is 2. it is belongs to Alkaline earth metal. valency of Alkaline earth metal is 2 because they have two electron in outermost shell, by removing these electron easily to gain nearest inert gas configuration.
In case of Beryllium after removing two electron it gain inert gas Electronic configuration like Helium which is stable Electronic Configuration.
Be (4) = 1S2 2S2
Be 2+ (2) = 1S2
He (2) = 1S2
Therefore third Ionization Energy is too much higher than the second Ionization energy.

Ionization energy (Ei) is the amount of energy required to remove an electron from a neutral gaseous atom or gaseous ion. Electrons are attracted to the positively charged nucleus; therefore removing an electron requires energy. The process is endothermic, and so ionization energies have a positive value. The first ionization energy (Ei1) is the energy associated with the removal of an electron from the neutral gaseous atom. The reaction is represented for the generalized atom X as X→X++e− The amount...

The first ionzation energy generally increases from left to right across a period. However, there are some exceptions to this trend. For example, boron has a smaller ionization energy than beryllium even though it lies to the right of it in the same period Select the statement that explains this exception to the trend in ionization energy. The 2p electron in boron experience a greater effective nuclear charge than the 2s electrons in beryllium, meaning it is easier to remove...
