Boron is quite distinct element in … All of them has 3 electrons in the outermost shell which has the electronic configuration of ns 2 np 1. A metalloid is a chemical element with properties in between those of metals and non metals. Which of the following is not a metalloid? For example, boron acts as a nonmetal when reacting with sodium yet as a metal when reacting with fluorine. Head-on crash kills 7 kids, 2 adults in central California The metalloids in this list include boron, silicon and tellurium. Industrially, very pure boron is produced with difficulty because of refractory contamination by carbon or other elements. Sodium benzoate B. D) All of the above. BORON In the quest for novel drug candidates, researchers have substituted boron for its neighbour carbon in numerous classes of drug molecules (1,2). Elements sometimes also classified as nonmetals are the metalloids boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At). ill give brainliest please answer this - the answers to estudyassistant.com What metalloid has commonly been used as an insecticide due to its effectiveness as a poison. C) antimony . However, boron has one distinct difference in that its 2s 2 2p 1 outer electron structure gives it one less valence electron than it has valence orbitals. Like a non-metal, boron has a low concreteness and forms covalent bonds with other non-metallic substances. B) boron . Boron, silicon, germanium, arsenic, antimony, and tellurium are commonly recognised as metalloids. Name: Boron Symbol: B Atomic Number: 5 Atomic Mass: 10.811 amu Number of Protons/Electrons: 5 Number of Neutrons: 6 Date of Discovery: 1808 Discoverer: Sir Humphry Davy, J.L Gay-Lussac Uses: heat resistant alloys Classification: Metalloid Group 14: Carbon Group. The more an element is to the left of the Periodic table, the more it is metal. Borane is a related term of boron. The only exception to this is Aluminum, which is classified under "Other Metals". Explain why the rest of the group has metallic behavior but boron does not. The other elements in this group have more electron shells, so it is much easier for them to lose their valence electrons and they behave like metals. Metalloid. Some of the metalloids, such … Boron is a metalloid, intermediate between metals and non-metals. Herein, an attempt has been made to review this topic due to awakening interest on metalloids for the treatment of human diseases. Please, keep in mind the following Periodic table rules. A.
