Mercury atomic symbol

Mercury and its compounds have a long and rich history. Its atomic symbol is derived from the Greek name Hydragyrum meaning watery silver. The English word for the element comes from the name of the Roman messenger god because of mercury s liquid mobility and quickness . As early as the second millennium b.c., mercury may have been recovered and nsed in Egypt. Recovery of the element from... 

Ions aren t always monoatomic, composed of just one atom. Ions can also be polyatomic, composed of a group of atoms. For example, take a look at Table 6-3. Notice an3rthing about the Mercury(I) ion Its ion symbol, Hg2 shows that two mercury atoms are bonded together. This group has a 2+ charge, with each mercury cation having a 1+ charge. The mercurous ion is classified as a polyatomic ion.

Mercury - the atomic number is 80 and the chemical symbol is Hg. The name derives from the Roman god Mercury , the nimble messenger of the gods, since the ancients used that name for the element, which was known from prehistoric times. The chemical symbol, Hg, derives from the Greek hydragyrium for liquid silver or quick silver. 

The Names and Symbols of the Elements. The names of the ele ments are given in order of atomic number in Table 4-1. The chemical symbols of the elements, used as abbreviations for their names, are also given in the table. These symbols are usually the initial letters of the names, plus another letter when necessary. In some cases the initial letters of Latin names are used Fe for iron (ferrum), Cu for copper (cuprum), Ag for silver (argentum), Au for gold (aurum), Hg for mercury (hydrargyrum). Th system of chemical symbols was proposed by the great Swedish chemist Jons Jakob Berzelius (1779-1848) in 1811. 

Mercury is a silver-colored metallic element in fluid form (symbol Hg atomic no. 80). Its symbol derives from the Greek name for the element hydrargyros. It is found as the sulfide salt in cinnabar, the source of the pigment vermilion. 

For simple elementary substances the smallest particle is called an atom. An atom is very small indeed a sheet of iron 1 //m thick would be 4300 atoms thick. These simple substances, which have as their smallest particle an atom, are called elements. There are 92 elements found in nature, including such commonplace materials as oxygen and carbon, sulphur and mercury, iron and lead. The Latin names of these elements can be abbreviated to one or two letters. These abbreviations are internationally recognized as symbols for the elements, e.g. O for oxygen, C for carbon, S for sulphur, Hg for mercury (hydrargyrum), Fe for iron (ferrum) and Pb for lead (plumbum). The 92 elements are listed by their symbols in a table called the Periodic Table (Fig. 1). The elements listed in vertical columns behave similarly in a chemical sense. The elements are given atomic numbers from 1 to 92. 

Mercury is an element with the symbol Hg and atomic number 80. It is a heavy, silver metal that exists as a liquid at standard conditions for temperature and pressure. See Fig. 3 [17]. 

In 1849 Gerhardt defined equivalent in the same way as Laurent, saying that a metal such as iron, copper, or mercury, can have different equivalents in different salts. He, also Laurent and Griffin, used different symbols for these ferrous—Fe, ferric = Fe =fe or Fee ferrous oxide FeaO (Fe =28), ferric oxide fe20. Laurent even had an iron molecule of 24 small atoms ferricum (f ) , ferrous oxide (f )(f )0, ferric oxide (P)(f )0 etc. 

List the symbol and atomic number corresponding to each element. (a) carbon (b) nitrogen (c) sodium (d) potassium (e) copper 46. List the symbol and atomic number corresponding to each element (a) boron (b) neon (c) silver (d) mercury (e) curium... 

Let us make a few observations about these rules before we look at some examples of their use. First, in Rule 1 the uncombined element is an element that is in the free elemental state, or the state of the element when it is not combined with any other element. For most elements, this is shown by the use of the symbol of the element, as found in the periodic table. For example, the oxidation numbers of silver metal (Ag), radon gas (Rn), and mercury liquid (Hg) would be 0. However, there are some elements whose free elemental state refers to diatomic molecules, or molecules that consist of two atoms of the element that are covalently combined. This list includes hydrogen gas (H2), fluorine gas (F2), nitrogen gas (Nj), oxygen gas (O2), chlorine gas (CI2), bromine liquid (Br2), and iodine solid (I2). Thus, whenever these diatomic symbols are observed, these substances are in their free elemental state and the correct oxidation number to be assigned would be 0. 

Ions can be polyatomic, composed of a group of atoms. For example, take a look at Table 5-3 in the preceding section. Notice anything about the mercury (1) ion Its ion symbol,...
