the most used definition of electronegativity is that an element's electronegativity is the power of an atom ''when in a molecule to attract electron density to itself. The electronegativity depends upon a number of factors and in particuler as the other atoms in the molecule. The first scale of electronegativity was developed by Linus Pauling and on his scale'''mercury has a value of '''2.00on a scale running from from about 0.7 (an estimate for francium) to 2.20 (for hydrogen) to 3.98 (fluorine). Electronegativity has no units but "Pauling units" are often used when indicating values mapped on to the Pauling scale.

Is Mercury a diatomic element?
Yes, mercury can be a diatomic element. Mercury is a diatomic element when it is in the form of a mercury(I) ion, or Hg2, when each Hg atom has a 1+ charge, resulting in a total charge of 2+.
What is the name of Hg2NO32 show work?
Hg2(NO3)2 is the chemical formula of mercury(I) nitrate.
What is the name of the grey precipitate in the confirmatory test for mercury?
dimeric mercury ion Hg2+ 2 + 2 KI → Hg2I2 + 2 K+2 Hg2+ 2 + 2 NaOH → 2 Hg 2O + 2 Na+ + H2O Confirmation test for mercury:Hg2+ + 2 KI (in excess) → HgI2 + 2 K+HgI2 + 2 KI → K2[HgI4] (red precipitate dissolves)2 Hg2+ + SnCl2 → 2 Hg + SnCl4 (white precipitate turns gray)
Are polyatomic ions positively charged?
Most polyatomic ions have a negative charge. There are only 2 positive polyatomic ions; Mercury(I) ion and Ammonium ion. False.
Is mercurous ion a cation?
Basically mecuric ions exist in solution as Hg2+,Hg22+ <P> <P>Neither, in it's natural state. Mercury (Hg) is an element, and exists as a neutral atom, unless it combines with other elements. In this case, it combines with negative elements (for example chloride -Cl) and then it has a positive charge (Hg)++(Cl-)2. Then, it is a cation.</P>
Is Mercury a diatomic element?
Yes, mercury can be a diatomic element. Mercury is a diatomic element when it is in the form of a mercury(I) ion, or Hg2, when each Hg atom has a 1+ charge, resulting in a total charge of 2+.
