<span>The number of lone electron pairs on the central atom of molecule having a linear molecular geometry such as CIF2- is three (3). In studying chemistry, linear molecular geometry describes the geometry around a central atom bind to two other atoms or ligands placed to a bond-angle of 180 degrees.</span>
Alloys are mixtures of metals and other elements, which still keeps many characteristics of metal.
Alloys are sometimes desirable as they have some properties that the original metals don't, for example more flexibility or less fragility. Steel is such an alloy: it prevents movement of iron parts, making it stronger.
