Group 13 Elements: The Boron Family - GeeksforGeeks

WebOn moving down a group, ionization enthalpy generally decreases due to an increase in the atomic size and shielding. Thus, on moving down group 13, ionization enthalpy decreases from B to Al. But, Ga has higher ionization enthalpy than Al. Al follows immediately after s–block elements, whereas Ga follows after d–block elements. WebAnswer: D. Solution: Since the valence shell of the elements in group 17 has seven electrons, their general electrical configuration is ns 2 np 5, or ns2np2 x 〖 np 〗2 y 〖 np 〗1 z,, where n=2 to 6 . As a result, they have one less electron than the nearby inert gas configuration. So, option D is the correct answer. Q3.
