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 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>

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)

Is Hg2 ionic or covalent?
Hg2 is a diatomic molecule consisting of two mercury atoms bonded together. The bond in Hg2 is considered metallic in nature, so it is more accurately described as metallic rather than purely ionic or covalent.
How many electrons does hg2 plus have?
Hg2+ has 118 electrons. Each mercury (Hg) atom contributes 80 electrons, so two atoms in Hg2+ contribute a total of 160 electrons. Since it is a +2 cation, it has lost 2 electrons, resulting in a total of 118 electrons.
