Maximum covalency of beryllium
WebThese elements also have only 4 valence orbitals available (2s and 2p) for bonding as compared to the 9 available (3s, 3p, and 3d) to the other members of the respective groups, so their maximum covalency is 4. … Webberyllium also exhibits unique chemical properties. It is the s-block element with by far the highest electronegativity, which is most closely matched by al uminium and zinc (Table 1). 4 Hence, the covalency of beryllium elem ent bonds is unusually high. The …
