A compound consisting of this element and three hydrogens is added to an alkene as part of a two-part process that creates alcohols in an anti-Markovnikov manner.
Brain tumors can be treated using a form of neutron capture therapy that utilizes one of this element's isotopes referred to as its "enriched" version. One atom of this element is present in an acid that is typically encountered adjoined to diethyl ether. It is theorized that the "wurtzite" modification of this element's nitride may exceed the hardness of diamond. The "styx number" is a method to aid in counting electrons in bonds involving this element. An acid containing one atom of this element is (*) coupled with aryl- or vinyl-halides in a reaction that is catalyzed by palladium. A compound consisting of this element and three hydrogens is added to an alkene as part of a two-part process that creates alcohols in an anti-Markovnikov manner. This element's hydride can take on closo-, nido-, and arachno- configurations. This element can only bond with six electrons, thereby violating the octet rule. For 10 points, identify this element with atomic number five.
