Metal,Nonmetal,orMetalloid Introduction:The sections of the periodic table reflect the electron configurations of the elements and the sublevels occupied by the electrons. It is the electron configuration of the atom that determines its chemical reactivity. An element’s position in the periodic ...
Atoms generally become larger, ionization energy falls, and metallic character increases.[74] The net effect is that the location of the metal–nonmetal transition zone shifts to the right in going down a group,[71] and analogous diagonal similarities are seen elsewhere in the periodic table, as...
Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. There is no single property which can be used to unambigu
Metalloid, or semi metal, is a term used in chemistry when classifying the chemical elements. On the basis of their general physical and chemical properties, nearly every element in the periodic table can be termed either a metal or a nonmetal. However, a few elements with intermediate properti...
What is the first element in the periodic table? Identify the group and period for each of the following. Refer to the periodic table. Label each as a metal, nonmetal, or metalloid. (a) C (b) Po (c) Cr (d) Mg (e) B Give the symbol for each of the following elements and class...
Answer to: Classify bromine as one of the following: a. nonmetal b. main group metal c. transition metal d. metalloid e. none of the above By...
metalloids; microbial bioremediation; microbial consortia; microbial ecology; tolerance gene and protein 1. Introduction 1.1. Metalloids Metalloid elements have some physical and chemical characteristics between metal and nonmetal elements. Metalloids included arsenic (As), antimony (Sb), boron (B), ...
A metalloid is an element intermediate in properties between the typical metals and nonmetals. It is a nonmetal that can combine with a metal to form an alloy. The six commonly recognized metalloids are boron, silicon, germanium, arsenic, antimony, and tellurium. The most common semimetal is ...
