![]() These shells are also given naming convention which helps in the description of an electron that is present in the atomic shells.Īll the electrons in the atom have some quantum numbers which are used to describe its location and thus also help in inferring the properties that the element is going to show. The electrons are placed in shells according to the energy. It has atomic number of 80 and a molecular weight of 200.59 and belong to the Group 12 (Zinc group, II b) of the periodic table 2. Mercury have boiling and melting points of 356.9 C and -38.87, respectively. And have the unique characteristic of being liquid at room temperature. The distribution of the electron is similar to how the planets move in our solar system. Mercury is a silver-white dense metal with a mirror like appearance. These electrons are present in the shells according to the energy. Note: The atom consists of electrons which are present inside the atoms in specific orbits or shells. Number of electron \ Mass number $ - $ atomic number So to get the number of electrons in the element we just need to decrease the number of protons from the summation amount of mass number Mercury is a chemical element of the periodic table with chemical symbol Hg and atomic number 80 with an atomic weight of 200.592 u and is classed as a. ![]() The atomic number of the element is the number of protons that are present in the atom. It is silvery in color and is classified as a transition metal. The red pigment vermilion is extracted by grinding either natural cinnabar or synthetic. The mass number of the atom is the summation of the number of protons and neutrons. Meet the element mercury which is liquid at room temperature with an atomic number of 80. The symbol of mercury is Hg and atomic number is 80. Mercury $204$ indicates that the mass number of this isotope of mercury is $204$. ![]() Natural deposits of mercury-bearing minerals, usually in the form of cinnabar, a sulfide of mercury, have been found throughout the world. This electronic configuration is responsible for various properties that the atom shows. mercury atomic number 30 48 80 atomic weight 65.409 112.411 200.59 melting point (☌) 419.53 321.07 38.83. Mercury, also called quicksilver (chemical symbol Hg, atomic number 80), is a chemical element and transition metal that at room temperature and pressure is a heavy, silvery liquid. The atomic structure of the atom depends on the electronic configuration in which the electrons are arranged inside the atoms. Hint: According to Dalton’s theory the atom is the most basic form of matter but the atom contains various subatomic particles like the electrons and protons.
