The chemical symbol for Sodium is Na. Sodium is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell that it readily donates, creating a positively charged atom—the Na+ cation.
Nope, that isn't a typo. You've heard of the periodic table of elements? Well, check out this hilarious table of condiments that periodically go bad. From Condiment No. 1 (Mayonnaise, which the table says goes bad in 3 months) to Condiment
click on any element's name for further information on chemical properties, environmental data or health effects.. This list contains the 118 elements of chemistry. •The groups in the Periodic Table are numbered from 1 to 18. •Elements in the same group have the same number of valence electrons. •Example: Sodium and potassium are both found in group 1 which means that they both have 1 valence electron KMP/ChemUnit/SK017-10/11 4 4 Group number = number of valence electron (if the element is in block s and d) OR Compare Sodium vs Chlorine of the Periodic Table on all their Facts, Electronic Configuration, Chemical, Physical, Atomic properties.

On 1 May 2014 a paper published in Phys. Rev. Lett by J. Khuyagbaatar and others states the superheavy element with atomic number Z = 117 (ununseptium) was produced as an evaporation residue in the 48 Ca and 249 Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column (Figure 2). Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name.

The Periodic Table • Periodic Law - When the elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties • Modern Periodic consists of: Periods - Horizontal rows of the periodic table (side to side) Groups or families - – vertical (up and down)
