Is Hg a metal?
mercury (Hg), also called quicksilver, chemical element, liquid metal of Group 12 (IIb, or zinc group) of the periodic table.
What type of metal is Hg?
Mercury is a naturally-occurring chemical element found in rock in the earth's crust, including in deposits of coal. On the periodic table, it has the symbol "Hg" and its atomic number is 80. It exists in several forms: Elemental (metallic) mercury.
Is Hg nonmetal or metal?
Its chemical symbol (Hg) comes from hydrargyrum from the Greek word hydrargyros meaning 'water' and 'silver'. Mercury is classified as a "Transition Metal" as it is ductile, malleable, and is able to conduct heat and electricity.

Is mercury wet?
It's pure Terminator, and not “wet” in the sense that water is wet. One reason is because the surface tension within mercury is so strong that drops of it adhere to each other more than they'd break ranks to adhere to another surface.
Why mercury is not a metal?
Mercury is a metal because is has free electrons as do all metals. As a result it is a good conductor of electricity as are all metals. that's why it is called metal. it's a different thing that it is in liquid state at room temperature.

What is the lightest element on the periodic table?
With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.
What is the crystal structure of hydrogen?
A possible crystal structure of Hydrogen is hexagonal structure.
How many protons and electrons are in hydrogen?
Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. The chemical symbol for Hydrogen is H.
What is the atomic mass of an atom?
The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10 -12 of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance.
How to determine the stability of an isotope?
To determine the stability of an isotope you can use the ratio neutron/proton (N/Z). Also to help understand this concept there is a chart of the nuclides, known as a Segre chart. This chart shows a plot of the known nuclides as a function of their atomic and neutron numbers. It can be observed from the chart that there are more neutrons than protons in nuclides with Z greater than about 20 (Calcium). These extra neutrons are necessary for stability of the heavier nuclei. The excess neutrons act somewhat like nuclear glue. Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3.
How are the chemical properties of a solid, liquid, gas, and plasma determined?
The chemical properties of the atom are determined by the number of protons, in fact, by number and arrangement of electrons. The configuration of these electrons follows from the principles of quantum mechanics. The number of electrons in each element’s electron shells, particularly the outermost valence shell, is the primary factor in determining its chemical bonding behavior. In the periodic table, the elements are listed in order of increasing atomic number Z.
What is the atomic radius of hydrogen?
The atomic radius of Hydrogen atom is 31pm (covalent radius).
