Sodium chemical symbol

Sodium [7440-23-5] Na, an alkali metal, is the second element of Group 1 (lA) of the Periodic Table, atomic wt 22.9898. The chemical symbol is derived from the Latin natrium. Commercial iaterest ia the metal derives from its high chemical reactivity, low melting poiat, high boiling poiat, good thermal and electrical conductivity, and high value ia use. 

Na The chemical symbol for sodium NA Noradrenaline also known as norepinephrine... 

The number of electric charges possessed by an ion (corresponding to its valency) is indicated by writing as a superscript one or more positive or negative signs after the chemical symbol for the element or the radical concerned according as to whether the ion is positive or negative in character. Thus, Na+ depicts the univalent sodium ion, Cl the univalent chloride ion, SO4- the divalent sulfate ion, and Cu2+ the divalent cupric ion. 

Sodium - the atomic number is 11 and the chemical symbol is Na. The name derives from the English soda and Latin sodanum for headache remedy . The chemical symbol Na derives from the Latin natrium for natron (soda in english) . It was discovered in 1807 by the English chemist Humphry Davy from electrolyosis of caustic soda (NaOH). 

Chemists express atoms and molecules as letters or series of letters. Each element usually has a one- or two-letter chemical symbol. The letter H, for example, stands for the element hydrogen. Na stands for the element sodium. 

Sodium (Na) The chemical symbol for sodium comes from the Latin natrium, which means swimmer. When a small piece of sodium is placed in water, it skitters around the surface, like a swimmer in a pool. It reacts with water to give sodium hydroxide and hydrogen gas. The hydrogen sometimes ignites. Larger samples of sodium simply explode. Sodium ions, along with potassium ions, are required for muscle contractions. 

Like many elements, sodium s chemical symbol seems to bear no relation to its name. In such cases the symbol often derives from the Latin if the Roman Empire used one of its minerals, as in this case natrium, or metal of soda , which was in turn coined from natron, a naturally occurring hydrous sodium carbonate mineral. The name sodium also came from the Latin sodanum, a headache remedy. 

For convenience, each element is given a chemical symbol that acts as a chemical shorthand in talking and writing about it and its reactions. The symbol always comprises one or two letters the first letter is a capital, which may correspond to the initial letter of the element s name Mg = magnesium, Ca = calcium, C = carbon, O = oxygen, H = hydrogen, S = sulphur, He = helium. Some chemical symbols are less obvious because they are derived from Latin names for the elements Pb = lead (plumbum), Fe = iron (ferrum), Na = sodium (natrium), K = potassium (kalium). 

The Egyptians called soda natron. Much later, the Romans used a similar name for the compound, natrium. These names explain the chemical symbol used for sodium, Na. 

The chemical symbols of the periodic table make it easy to write the formulas for chemical compounds. For example, table salt, or sodium chloride, is composed of one part sodium (Na) and one part chlorine (Cl), and its chemical formula is NaCl. Water is composed of two parts hydrogen (H) to one part oxygen (O), and its formula is H2O. 

The build-up of the third period, from sodium to argon, is an echo of what happened in the second first the one 3s orbital is filled, and then the three 3p orbitals. As the number of electrons in an atom reaches 15 or 20, it is frequently the practice to explicitly include only those electrons added in the building up beyond the last preceding noble-gas element. The configuration of that noble gas is then represented by its chemical symbol enclosed in brackets. The ground-state configuration of silicon, for example, is written [Ne]3s 3p using this system. 

The fact that the French and Italians call sodium chloride chlorure de sodium and cloruro di sodio explains why one will occasionally find equations where NaCl appears as ClNa. This is true of so many compounds that some chemical equations in French and Italian often look as if someone just jumbled all the chemical symbols. 

Most of the symbols are clearly derived from the English name of the element, but a few come from older Latin names, such as iron (Fe, ferrum), potassium (K, kalium), and sodium (Na, natrium) It is important to know the names and symbols of the most common elements, because chemical symbols are used in all areas of science. Practicing with flashcards is the easiest way to memorize the symbols and names. 

The symbol Na provides more information than i iNa. The mass number plus the chemical symbol identifies a specific isotope of Na (sodium) while combining the atomic number with the chemical symbol tells you nothing new. Can other isotopes of sodium have different atomic numbers ... 

We can generalize what we have just done for the electron configuration of sodium. In writing the condensed electron configuration of an element, the electron configuration of the nearest noble-gas element of lower atomic number is represented by its chemical symbol in brackets. For lithium, for example, we write... 

Give the chemical symbols for the following elements (a) aluminum (b) sodium (c) bromine (d) copper (e) silicon (f) nitrogen (g) magnesium (h) helium. 

The names of the elements are given 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 Na for sodium (natrium), K for potassium (kalium), Fe... 

Most chemical symbols are based on the English name of the element. For example, the symbol for carbon is C for silicon, Si and for bromine, Br. Some elements, however, have symbols based on their Latin names. For example, the symbol for potassium is K, from the Latin kalium, and the symbol for sodium is Na, from the Latin natrium. Additional elements with symbols based on their Greek or Latin names include the following ... 

For convenience, chemists use symbols of one or two letters to represent the elements. Only the first letter of an element s chemical symbol is capitalized. A list of the elements and their symbols appears on the inside front cover of this book. The symbols of some elements are derived from their Latin names— for example, Ag from argentum (silver), Pb from plumbum (lead), and Na from natrium (sodium)— while most of them come fiom their English names— for example, H for hydrogen, Co for cobalt, and Br for bromine.
