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.
What family does antimony belong to?
Antimony (Sb), a metallic element belonging to the
nitrogen group
(Group 15 [Va] of the periodic table).
Is antimony a poor metal?
Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is
a poor conductor of heat and electricity
, it is stable in dry air and is not attacked by dilute acids or alkalis.
Is bismuth a metal?
Bismuth is a
white, crystalline, brittle metal
with a pinkish tinge. Bismuth is the most diamagnetic of all metals, and the thermal conductivity is lower than any metal except for mercury.
Is mercury a metal?
Elemental or metallic mercury is a
shiny, silver-white metal
, historically referred to as quicksilver, and is liquid at room temperature. It is used in older thermometers, fluorescent light bulbs and some electrical switches.
Which is the rarest element on the Earth?
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element
astatine
Is antimony a poison?

Is bismuth toxic to humans?
In the clinic, depending on the administration time of bismuth,
its toxicity can be roughly divided into acute and chronic exposures
. Both exposure doses can cause neurotoxicity, gastrointestinal toxicity, nephrotoxicity, hepatotoxicity, and increased bismuth concentration in blood.
What does bismuth taste like?
Maybe the most bizarre application for bismuth is its use in the popular over-the-counter stomach medicine, Pepto-Bismol. That’s right, the
minty-tasting
pink stuff that treats your heartburn contains over a quarter of a gram per dose.
Can you touch mercury?
If you touch it, a small amount may pass through your skin, but
not usually enough to harm you
. Mercury is most harmful when you breathe in the vapors that are released when a container is open or a spill occurs. Pregnant women, infants and young children are particularly sensitive to the harmful effects of mercury.
What happens if mercury touches gold?
Freddie Mercury may have had the golden voice, but real mercury, that endlessly entertaining and dangerous liquid metal, has the golden touch. That is, if it touches gold
it will immediately break the lattice bonds of the precious metal and form an alloy in a process
known as amalgamation.
Where do you find mercury in everyday life?
Humans are exposed to mercury in a variety of ways. The air is contaminated with mercury from volcanoes, coal-fired power plants, crematoriums, and medical or municipal waste incinerators. Everyday objects such as
fluorescent light bulbs, disk batteries, and thermometers
may contain mercury.
Is antimony a rare earth?
Although
antimony is not a rare earth
, the U.S. Government considers it to be critical and strategic due its military applications. … Antimony metal is alloyed with lead as a hardener for bullets and for lead-acid deep-cycle industrial batteries for trucks and heavy equipment.
Is tellurium a rare earth?
Tellurium is one of the least common elements on Earth. Most rocks contain an average of about 3 parts per billion tellurium, making
it rarer than the rare earth elements
and eight times less abundant than gold.
What elements do not exist on Earth?
Technetium
. The first element that was synthesized, rather than being discovered in nature, was technetium in 1937. This discovery filled a gap in the periodic table, and the fact that no stable isotopes of technetium exist explains its natural absence on Earth (and the gap).
