Periodic TableIonization Energy Trend7Choose the best answerGallium has a slightly higher first ionization energy than aluminium mainly because of:APoor shielding by the intervening 3d-electronsBGreater shielding by 4p-electronsCLower nuclear charge of galliumDA completely filled valence shell Like 0 Discuss 0Share
