Finally, IUPAC assigns collective names (lanthanoids and actinoids) and group numbering (1 to 18) and has investigated the membership of the group 3 elements. PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable.

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.
Ar. 19 /oganesson-chemistry-periodic-table-1740914/ Elements on the left side of the periodic table tend to lose their valence electrons in chemical reactions. Sodium (in Group 1), for example, tends av BF Thornton · 2015 · Citerat av 2 — that element 67 had been discovered — newly observed spectral was not unusual for the same element to be Stockholm county boasts Ytterby, the periodic table's YRIA NA. TUR, S. T. OCKHOLM. © 2015 Macmillan Publishers Limited.
The first 10 elements are as follows- Hydrogen (H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne). Mnemonic: Happy Henry Likes Beans Brownies and Chocolates Nuts Over Friday’s News. Group 1 and Group 2 elements are collectively called as s-block elements.
When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.
Finally, IUPAC assigns collective names (lanthanoids and actinoids) and group numbering (1 to 18) and has investigated the membership of the group 3 elements. PubChem is working with IUPAC to help make information about the elements and the periodic table machine-readable. The modern periodic table is sometimes expanded into its long or 32-column form by reinstating the footnoted f-block elements into their natural position between the s- and d-blocks, as proposed by Alfred Werner in 1905. Unlike the 18-column form, this arrangement results in "no interruptions in the sequence of increasing atomic numbers". 11 Na Sodium 22.990; 12 Mg Magnesium 24.305; 13 Al Aluminium 26.982; 14 Si Silicon 28.085; 15 P Phosphorus 30.974; 16 S Sulfur 32.06; 17 Cl Chlorine 35.45; 18 Ar Argon 39.948

The element symbol, Na, was shortened from the Latin name 'Natrium.' Swedish chemist Berzelius was the first to use the symbol Na for sodium in his early periodic table. History: Sodium does not usually appear in nature on its own, but its compounds have been used by people for centuries.

A modern version is shown in Figure \(\PageIndex{1}\). Most periodic tables provide additional data (such as atomic mass) in a box that contains each element’s symbol.
