Arsenic is a native element with the formula As and atomic number 33. Known since antiquity, arsenic is widely distributed in nature, although it is unusual in native form. It is classified as a semimetal, because it possesses some properties of metals and some of nonmetals. Crystals are rare, but when found they are rhombohedral.

Sulfur is the tenth most common element by mass in the universe, and the fifth most common on Earth. It (also spelled sulphur) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, atoms form cyclic octatomic molecules with a chemical formula S8.

The hardest known mineral, diamond is pure carbon. Its crystals typically occur as octahedrons and cubes with rounded edges and slightly convex faces. Crystals may be transparent, translucent, or opaque. They range from colorless to black, with brown and yellow being the most common colors. Other forms include bort or boart (irregular or granular black diamond) and carbonado (microcrystalline masses).

Antimony usually occurs in massive, leafy or granular form. It has a flaky texture that makes it shiny, silvery, bluish white and brittle. It occurs in rare, usually massive, leafy or granular form.

Graphite is like diamond, graphite is a form of native carbon crystalline with its atoms arranged in a hexagonal structure. Graphite is opaque and dark gray to black. It occurs as hexagonal crystals, flexible sheets, scales, or large masses.
