How do you find the atomic mass of antimony?
The chemical value was evidently given a preference when in 1969 the Commission recommended Ar(Sb) = 121.75(3). In 1989, the Commission adopted Ar(Sb) = 121.757(3) based on new mass-spectrometric measurements….Antimony.

Antimony/Atomic number
Why is antimony called antimony?
The name derives from the Greek, anti + monos for “not alone” or “not one” because it was found in many compounds. The symbol Sb comes from stibium, which is derived from the Greek stibi for “mark” because it was used for blackening eyebrows and eyelashes. Antimony has been known since ancient times.

How do you identify antimony?
- Antimony is a silvery-white metal that is found in the earth’s crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide.
- Antimony powder appears as a silvery or gray solid in the form of dust.
- Antimony(0) is an elemental antimony.
Why is it called antimony?
Word origin: Antimony was named after the Greek words anti and monos to mean “a metal not found alone.” The chemical symbol, Sb, comes from the element’s historical name, stibium. Discovery: Antimony was a known metal in the 17th century and was likely used even earlier.
What are the physical properties of antimony?
Physical properties. 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. The melting point of antimony is 630°C (1,170°F) and its boiling point is 1,635°C (2,980°F).
What is the mass number of antimony?
Antimony has 51 electrons and protons; thenumber of neutrons is specific for each isotope. Number of neutrons in an antimony isotope = Mass number – 51.
What is the definition of antimony?
Definition of antimony. 1 : stibnite. 2 : a trivalent and pentavalent metalloid element with atomic number 51 that commonly occurs in a brittle, metallic, silvery white crystalline form and that is used especially in alloys, semiconductors, and flame-retardant substances — see Chemical Elements Table.
What element is antimony?
Antimony is a naturally existing chemical element. Native antimony from Mexico. Antimony is a shiny gray metalloid which exists in nature as sulfide mineral stibnite. The atomic number of antimony is 51, and its chemical symbol is Sb, which is derived from the Latin term “stibium.”.
