C Carbon
Contributed by @plazmatter0430
A cube and two irregular chunks of Carbon
Al Aluminum
Si Silicon
Contributed by @plazmatter0430

Contributed by @plazmatter0430
Two different allotropes of Phosphorus: a small bottle of powdery red Phosphorus , 2 chunks of violet Phosphorus , and a bottle filled with small chunks of violet Phosphorus . The violet Phosphorus in this sample appears closer to a wine or light-red color.
Contributed by @plazmatter0430
Small piece of Violet Phosphorus. This piece appears to be a dark purple color.
S Sulfur
Contributed by @plazmatter0430
An unusual sample - a large, smooth cylinder of Sulfur
Cl Chlorine
Contributed by @plazmatter0430
In most cases, Chlorine , Bromine , and Iodine are the only Elements in the halogen group that people can get. f is overwhelmingly reactive and requires special equipment to contain, while at is overwhelmingly radioactive and has not been isolated in a sample large enough to see.
Ca Calcium
Contributed by @plazmatter0430
A bottle filled with heavily tarnished Calcium pieces and oil
Contributed by @plazmatter0430
Heavily tarnished chunks of Calcium metal under oil in a bottle. Calcium is difficult to keep shiny.
Mn Manganese
Contributed by @plazmatter0430
Heavily oxidized chips of Manganese, and a large slightly-brassy-tarnished chunk of Manganese
Zn Zinc
Contributed by @plazmatter0430
Zinc cube, two big ingots, and disc
As Arsenic
Contributed by @plazmatter0430
Tarnished chunk of Arsenic on a display pitri dish, and tarnished chunks in a bottle
Se Selenium
Contributed by @plazmatter0430
Multiple gray Selenium ingots, covered in small surface holes likely caused by bubbles when the ingots were cooling.
Contributed by @plazmatter0430
The two commonly encountered forms of Selenium: gray pellets and red powder in separate bottles.
Br Bromine
Contributed by @plazmatter0430
Three separate sealed ampoules of liquid and gaseous Bromine
Contributed by @plazmatter0430
Bromine in a spherical beaker in an ice bath. Bright orange vapor fills the beaker.
Contributed by @plazmatter0430
Bromine and Mercury , the two elements that are liquid at room temperature
Contributed by @plazmatter0430
In most cases, Chlorine , Bromine , and Iodine are the only Elements in the halogen group that people can get. f is overwhelmingly reactive and requires special equipment to contain, while at is overwhelmingly radioactive and has not been isolated in a sample large enough to see.

Many small pieces of dull gray Yttrium metal laid out on tissue paper
Zr Zirconium
Contributed by @plazmatter0430
Two chunks of Zirconium metal: a small wedge-shaped chunk, and a larger bent-cylinder shaped chunk with a bumpy surface
Ru Ruthenium
Contributed by @plazmatter0430
Small bead of shiny Ruthenium on a bamboo (or wooden) platter
Contributed by @plazmatter0430
Three small chunks and a bead of Ruthenium

Three beads of Osmium in the center, a bead of Ruthenium [in the row] above, a bead of Rhenium [in the column] to the left, and a bead of Iridium [in the column] to the right. This mirrors the relative positions of these elements in the periodic table.
Pd Palladium
Contributed by @plazmatter0430
1 gram bar of Palladium
Ag Silver
Contributed by @plazmatter0430
Silver bars and coins
Sn Tin
Contributed by @plazmatter0430
Acid-etched disc of Tin, showing its poly-crystalline inner structure
Sb Antimony
Contributed by @plazmatter0430
Antimony and Bismuth are members of the Pnictogen group. This photo shows their similar surface crystal structures. Antimony has a silvery sheen, and Bismuth a warmer sheen.
I Iodine
