Define valence electrons and explain the difference in valence orbitals for main group and transition metals. Elements in the same period generally have: A. similar chemical properties B. the same number of electrons in the outer major energy level C...
In contrast to transition metals, main-group metal elements such as Mg, Al, and Ga, generally exhibit a delocalized s/p-band, which is prone to broaden the adsorbate states22,24,25. Such interaction is thought to yield either too strong or too weak adsorption for adsorbates. This would po...
