Some field metal identifiion tests can be used to identify a piece of metal. It is necessary to know metal composition to produce a satisfactory weld. Metal workers and Welders must be able to determine various metal products so that proper work methods may be applied. For equipment, drawings (MWOs) should be available.

Lithium is part of the alkali metal group and can be found in the first column of the periodic table right below hydrogen. Like all alkali metals it has a single valence electron that it readily gives up to form a ion or compound. Characteristics and Properties At room temperature lithium is a soft metal that is silvery-white in color.
29.06.2017· A nonmetal is an element that does not have the properties of a metal. A metalloid is an element having intermediate properties of both metals and nonmetals. This is the main difference between metals nonmetals and metalloids. Key Areas Covered. 1. What is a Metal – Definition, Properties, Examples 2. What is a Nonmetal
The metal has a silvery color, is rather hard, and is prepared by electrolysis of fused chloride and calcium fluoride (to lower the melting point). Chemically it is one of the alkaline earth elements; it readily forms a white coating of nitride in air, reacts with water, burns with a yellow-red flame.
Nonmetal definition, an element not having the character of a metal, as carbon or nitrogen. See more.
The native elements are those minerals formed wholely from elements which occur in an uncoined state.No ionic or covalent bonding may join atoms of one element to atoms of another within the lattice structure of such a mineral. Usually only one type of atom is …
