Antimony is a lustrous, silvery , bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite (Sb 2 S 3 ).
What does antimony look like?
Antimony is a silvery-white, shiny element that looks like a metal . It has a scaly surface and is hard and brittle like a non-metal. It can also be prepared as a black powder with a shiny brilliance to it. ... A metalloid is an element that has characteristics of both metals and non-metals.
What kind of metal is antimony?
Antimony is a semi-metal . In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength.

Is antimony toxic to the body?
Antimony toxicity occurs either due to occupational exposure or during therapy . Occupational exposure may cause respiratory irritation, pneumoconiosis, antimony spots on the skin and gastrointestinal symptoms. In addition antimony trioxide is possibly carcinogenic to humans.
Which is the rarest element on the Earth?

What is barite used for?
Other Uses: Barite is also used in a wide variety of other applications including plastics, clutch pads , rubber mudflaps, mold release compounds, radiation shielding, television and computer monitors, sound-deadening material in automobiles, traffic cones, brake linings, paint and golf balls.
What rock is antimony found in?
The only significant ore mineral of antimony, stibnite (Sb 2 S 3 ), is widespread as an accessory mineral in gold-bearing quartz veins, particularly in veins that intersect the Silurian – Early Devonian Murrindindi Supergroup sedimentary rocks of the Melbourne Zone.
Is antimony used in mascara?
The Ancient Egyptians used antimony sulfide as a mascara. Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes.
Is antimony a heavy metal?
11 – Other heavy metals: antimony, cadmium, chromium and mercury.
Why is Tungsten W?
The chemical symbol for tungsten is W which stands for Wolfram . The name came from medieval German smelters who found that tin ores containing tungsten had a much lower yield. It was said that the tungsten devoured the tin “like a wolf”.
Why is antimony bad for you?
It has also been listed as a possible human carcinogen by the International Agency for Research on Cancer. Breathing air contaminated with antimony can cause eye and lung irritation, heart and lung damage , stomach pains, diarrhea, vomiting, and stomach ulcers.
Can antimony be absorbed through the skin?
Exposure to high levels of antimony trioxide or a mixture of antimony trioxide and pentoxide resulted in death in rabbits (Myers et al. 1978). Since the application area was occluded, the study suggests that at least some forms of antimony can be absorbed through the skin .
What are the symptoms of heavy metals in the body?
- Abdominal pain, nausea, vomiting, and diarrhea (the hallmark symptoms with most cases of acute metal ingestion)
- Dehydration.
- Heart abnormalities such as cardiomyopathy or abnormal heart beat (dysrhythmia)
- Nervous system symptoms (e.g. numbness, tingling of hands and feet, and weakness)
