• Boron, Chemical Element

    Boron is the first element in Group 13 (IIIA) of the periodic table. The periodic table is a chart that shows how the chemical elements are related to each other. The elements in this group are usually referred to as the aluminum family. Boron is quite different from other members of the family. One difference is that boron is not a metal.

  • The Elements of Group 13

    Boron behaves chemically like a nonmetal, whereas its heavier congeners exhibit metallic behavior. Many of the inconsistencies observed in the properties of the group 13 elements can be explained by the increase in Z eff that arises from poor shielding of the nuclear charge by the filled ( n − 1) d 10 and ( n − 2) f 14 subshells.

  • Control Rods in Nuclear Reactors

    However, Boron's mechanical properties are less than desirable for building a control rod structure, as it is a brittle, saltlike material. Also, B11 makes up the majority of natural Boron and has a negligible absorption, so Boron may need to be enriched to reach the necessary absorptivity.
