Dividing line between metals and nonmetals

Index Dividing line between metals and nonmetals

The dividing line between metals and nonmetals can be found, in varying configurations, on some representations of the periodic table of the elements (see mini-example, right). [1]

Alexander Smith (chemist)

Alexander Smith (11 September 1865 – 8 September 1922) was an American chemist, born in Edinburgh, Scotland.

Boron group

The boron group are the chemical elements in group 13 of the periodic table, comprising boron (B), aluminium (Al), gallium (Ga), indium (In), thallium (Tl), and perhaps also the chemically uncharacterized nihonium (Nh).

Gustavus Detlef Hinrichs

Gustavus Detlef Hinrichs (2 December 1836 – 14 February 1923) was a chemist and natural philosopher most widely known for his findings on periodic laws within the chemical elements.

Hadrian's Wall

Hadrian's Wall (Vallum Aelium), also called the Roman Wall, Picts' Wall, or Vallum Hadriani in Latin, was a defensive fortification in the Roman province of Britannia, begun in AD 122 in the reign of the emperor Hadrian.

Intermetallic

An intermetallic (also called an intermetallic compound, intermetallic alloy, ordered intermetallic alloy, and a long-range-ordered alloy) is a solid-state compound exhibiting metallic bonding, defined stoichiometry and ordered crystal structure.

Metal

A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material (an element, compound, or alloy) that is typically hard when in solid state, opaque, shiny, and has good electrical and thermal conductivity.

Metalloid

A metalloid is any chemical element which has properties in between those of metals and nonmetals, or that has a mixture of them.

Nonmetal

Apart from hydrogen, nonmetals are located in the p-block. Helium, as an s-block element, would normally be placed next to hydrogen and above beryllium. However, since it is a noble gas, it is instead placed above neon (in the p-block). In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks metallic attributes.

Periodic table

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, whose structure shows periodic trends.

Zintl phase

In chemistry, a Zintl phase is the product of a reaction between a group 1 (alkali metal) or group 2 (alkaline earth) and any post-transition metal or metalloid (i.e. from group 13, 14, 15 or 16).
