Question

Metals are used in many products because of the characteristic properties that most metals share. Which properties of the metal tungsten make it useful in the thin, glowing filaments of light bulbs? Tungsten is electrically conductive, ductile, and opaque. Tungsten is ductile, is malleable, and has a high luster. Tungsten is ductile, has a high melting point, and is electrically conductive. Tungsten has a high luster, has a high melting point, and is silver in color.

Answer 1

Tungsten is ductile, has a high melting point, and is electrically conductive.

Step-by-step explanation:

Metallic bonds are such that there is a free flowing electron cloud that is held by the metal cations. Tungsten can be easily beaten into fine wire making it a very ductile metal. The melting point of Tungsten is very high at 3422ºC. Tungsten does not melt even when it is at glowing temperature. Tungsten conducts electricity and glows.

Answer 2

I think the best answer among the choices is the third option. The properties which make tungsten useful in the thin, glowing filaments of light bulbs are it has a high melting point and is electrically conductive. Its melting point is around 1650 degrees Celsius. Of all metals, it is the highest and also it does not melt even though it is glowing.
