Expert Solution & Answer
Chapter EH, Problem 13R
Solution
Interpretation : The general trend in first ionization energies in group 2 is to be described and explained.
Concept Introduction : Ionization energy is the bare minimum of energy that an electron in a gaseous atom or ion needs absorb to escape from the nucleus. The elements of group 2 have two valence electrons.
The first ionization energies in group 2 elements usually decrease down the group.
The elements of group 2 include beryllium, magnesium, calcium, strontium, barium, and radon.
The group 2 elements are also called alkaline earth metals.
The ionization energy usually decreases down the group.
The
Outermost electrons can be easily removed because they are far from the nucleus.
Moving down a group, the shielding effect brought on by an expanding number of shells is the second reason that lowers the ionization energy.
