Is mercury a compound element or mixture?
Like lead or cadmium, mercury is a constituent element of the earth, a heavy metal. In pure form, it is known alternatively as “elemental” or “metallic” mercury (also expressed as Hg(0) or Hg0). Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts.
Is Hg 1 a compound?
There are relatively few mercury(I) or mercurous compounds. The mercury(I) ion, Hg22+, is diatomic and stable. Mercury(I) chloride, Hg2Cl2 (commonly known as calomel), is probably the most important univalent compound. It was used in antiseptic salves.
Is Hg a pure compound?
The element mercury is a pure substance. Nickel sulfate is also a pure substance but it is a compound of the elements nickel, sulfur, and oxygen.
Is Platinum an element?
Platinum (Pt), chemical element, the best known and most widely used of the six platinum metals of Groups 8–10, Periods 5 and 6, of the periodic table. A very heavy, precious, silver-white metal, platinum is soft and ductile and has a high melting point and good resistance to corrosion and chemical attack.
What is the formula of HG?
Mercury is a chemical element with symbol Hg and atomic number 80….6.1Element Forms.

What is the formula of Hg?
Is platinum a silver?
While at first glance both silver and platinum appear silver in color, the two metals are actually easily discernible to the naked eye. Both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance.
Which is bigger Hg 1 or Hg 2?
Hg2+ will have a size smaller than Hg+ because of increased effective nuclear charge in Hg2+ as compared to Hg+, on account of loss of second electron from Hg+. Hope this information will clear your doubt regarding atomic size.
What does the atomic number Hg stand for in Mercury?
It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents.
Which is an example of a homogeneous mixture?
Salt water is an example of a homogeneous mixture, as it contains two distinctive chemicals, a “salt,” which is most likely sodium chloride, NaCl, and water, H 2 O. These compounds can be separated by boiling the water, leaving the salt as a residue.
How are two elements present in a mixture?
Since two elements are present, this is a compound (carbon monoxide). Again, the elements are present in a one-to-one ratio, as neither elemental symbol has an explicitly-written subscript. A mixture is a blend of two or more elements or compounds, which have their own identities and properties.
Which is a compound with two elements in it?
Since two elements are present, this is a compound (sodium chloride, which is more commonly-known as “table salt.”) Note that the elements are present in a one-to-one ratio, as neither elemental symbol has an explicitly-written subscript.
