Review Constants 1 Periodic Table Part A en, beryllium, and boron are examples of s that can have less than an octet of is in a covalent compound. Even without an ydrogen achieves the helium configuration, refore noble-gas stability, by forming one nt bond. Beryllium and boron simply do not nough electrons to form the number of bonds to achieve an octet. Instead, Be uses its lence electrons to form two bonds, and B s three valence electrons to form three . None of these elements will have any lone How many lone pairs are on the central atom in BCI ? Express your answer numerically as an integer. View Available Hint(s) ents in the third row of the periodic table and nd can have more than an octet of electrons in alent compound. This can be explained by the ence of an empty d subshell available to these ents, which allows them to expand their nce to a number greater than eight.
