    Recognition status, as metalloids, of some elements in the p-block of the periodic table. Percentages are median appearance frequencies in the lists of metalloids. [n 2] The staircase-shaped line is a typical example of the arbitrary metal–nonmetal dividing line found on some periodic tables.

  5. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.

  6. Properties of nonmetals (and metalloids) by group - Wikipedia

    Arsenic is a poor oxidising agent (As + 3e → AsH 3 = –0.22 at pH 0). As a metalloid, its chemistry is largely covalent in nature, noting it can form brittle alloys with metals, and has an extensive organometallic chemistry. Most alloys of arsenic with metals lack metallic or semimetallic conductivity.

  7. Dividing line between metals and nonmetals - Wikipedia

    This line has been called the amphoteric line, [2] the metal-nonmetal line, [3] the metalloid line, [4] [5] the semimetal line, [6] or the staircase. [2] [n 1] While it has also been called the Zintl border [8] or the Zintl line [9] [10] these terms instead refer to a vertical line sometimes drawn between groups 13 and 14.

  8. 2-Bromopentane - Wikipedia

    en.wikipedia.org/wiki/2-Bromopentane

    2-Bromopentane is a bromoalkane and isomer of bromopentane. It is a colorless liquid. 2-Bromopentane is chiral and thus can be obtained as either of two stereoisomers designated as ( R )-2-bromopentane and ( S )-2-bromopentane, or as a racemic 1:1 mixture of the two enantiomers .

    For example, for the compound FeCl 3, the cation, iron, can occur as Fe 2+ and Fe 3+. In order for the compound to have a net charge of zero, the cation must be Fe 3+ so that the three Cl − anions can be balanced (3+ and 3− balance to 0). Thus, this compound is termed iron(III) chloride.
