Interpretation : The trends in the first ionization energies of the group 13 elements are to be described.
Concept Introduction : Group 13 consists primarily of metals with a silvery-white color. Group 13 elements all have three valence electrons whose electronic configuration ends with
Down the group 13 elements, the first ionization energy decreases.
The ionization energy is the least amount of energy an electron in a gaseous atom or ion must absorb to escape the nucleus's influence.
Usually, ionization energy rises across the period and down the group decreases.
Going down the group, the first ionization energies for group 13 elements typically drop.
So, boron will have higher first ionization energy among the group 13 elements.
