Why is Hg a liquid?
The electrons in mercury atom are bound more tightly than usual to the nucleus. The s electrons are moving so fast and close to the nucleus. Mercury is reluctant to form bonds and shows low melting point. So Hg exists in liquid state unlike other D-block elements.
Is Hg a nonmetal?
Mercury is the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It is a heavy, silvery-white liquid metal. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity.
Why is mercury called quicksilver?
Mercury has high molecular motion and mobility, hence it is known as quicksilver.

Why formula of mercurous chloride is Hg2Cl2?
Preparation and reactions. Mercurous chloride forms by the reaction of elemental mercury and mercuric chloride: Hg + HgCl2 → Hg2Cl. It can be prepared via metathesis reaction involving aqueous mercury(I) nitrate using various chloride sources including NaCl or HCl.
What is the oxidation state of copper in cuso3?
We could start from a knowledge that the sulphate ion has a 2- charge, so the copper ion must have a 2+ charge and hence a +2 oxidation number. We could substitute in the oxidation numbers of the sulphur and oxygen atoms, and apply the rule that in a compound the sum of all the oxidation numbers must come to zero.
Is SnCl4 ionic or covalent?

How many neutrons does Hg2+ have?
How many protons, neutrons, and electrons are in 20080Hg2+ ? Here, we have 80 protons and 200 – 80 = 120 neutrons. The “2+” charge tells us that we have lost two electrons. So there are 80 – 2 = 78 electrons.
What is the oxidation state of Mn in MnO4 −?
We know that the charge on an oxygen atom is −2. Sum of all the oxidation numbers in a polyatomic ion is equal to the charge on the ion. Thus, the total charge on the polyatomic anion is −1. Thus, the oxidation number of Mn in MnO−4 is +7.
What is the oxidation state of cr2o72 −?
The sum of the oxidation numbers in Cr2O72–, a polyatomic ion, is -2, the charge of the ion. There are seven oxygen atoms, so the total charge is − 2⋅7 = − 14. So, a chromium atom here has an oxidation number of + 6.
What is the oxidation state of Mn in MnO4 2 and MnO4?
Oxidation state of O is -2. [MnO4]2- is an ion having charge of -2. Mn has oxidation state of +6.

What is the density of Hg?
Mercury has a density of 13.5 g/mL, which is about 13.5 times denser than water (1.0 g/mL), so a small amount of mercury like this feels unexpectedly heavy. Mercury also has a very high surface tension, so small droplets of mercury form nearly spherical beads on glass.
Why is Mercury called Quicksilver?
Mercury has high molecular motion and mobility, hence it is known as quicksilver.
