sulphur

Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.

carbon

The physical and chemical properties of carbon depend on the crystalline structure of the element. Its density fluct for diamondCarbon is a soft, dull gray or black non-metal that you can scratch with a fingernail. Th density of carbon as graphite is 2.267 g/mL, which means it will sink in water. Chemical Properties: Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide).

phosphorus

Its melting point is 44.1°C (111°F) and its boiling point is 280°C (536°F). It has a density of 1.88 grams per cubic centimeter. If kept in a vacuum, it sublimes if exposed to light.Physical properties are usually those that can be observed using our senses such as color, luster, freezing point, boiling point, melting point, density, hardness and odor. The Physical Properties of Phosphorus are as follows: White phosphorous is white, waxy solid.White phosphorus is a waxy, transparent solid. Its melting point is 44.1°C (111°F) and its boiling point is 280°C (536°F). It has a density of 1.88 grams per cubic centimeter. If kept in a vacuum, it sublimes if exposed to light

silicon

Color : Pure silicon is a hard, dark gray solid.

Phase: Solid.

Luster: A metallic shine or glow.

Allotropic: Silicon has two allotropic forms, a brown amorphous form, and a dark crystalline form.

Solubility: Soluble in hydrofluoric acid and alkalis.physical properties such as hardness, color, melting and boiling point, and reactivity. Silica under normal conditions of temperature and pressure is a solid, crystallized mineral.

hope uh liked my answer

It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.The physical and chemical properties of carbon depend on the crystalline structure of the element.
