11: Sodium - Natrium [Na] Group: 1 Period: 3 Atomic number: 11 Atomic mass: 22.98976928 Configuration: [Ne] 3s 1 Atomic radius: 190 pm Covalent radius: 166 pm Electron affinity: 52.8 eV Ionization energy: 5.1391 eV Electronic term: 2 S 1/2 Mass fraction in the earth crust: 0.023 Mass fraction in the earth space: 0.00002 Electronegativity: 0.93
In the Periodic table it is in column 1 (alkali metals), and shares with the other six elements in that column that it has a single electron in its outer shell, which it readily donates, creating a positively charged atom - a cation.
It is made of two elements which are on the periodic table: sodium (Na) and chlorine (Cl). 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 - … 2021-03-03 Chemical elements listed by atomic mass The elements of the periodic table sorted by atomic mass. 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.
All the Selina Concise Chemistry questions have been solved in detail by experts and steps also have been explained well. (a) Na is bigger than Mg. This is because on moving from left to right in a period, there is an increase in the no. of electrons due to increase in the atomic number. So. Na is bigger than Mg. (b) (i) The most metallic element is Na and most non-metallic element is Cl in out of these elements.
The periodic table's name comes from the fact that it arranges the elements into repeating sets, otherwise known as The periodic table's name comes from the fact that it arranges the elements into repeating sets, otherwise known as "periods
Its only stable isotope is 23 Na. The free metal does not occur in nature, and must be prepared from compounds. The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.
Sodium (atomic number 11, symbol Na) is a metal and a chemical element that was discovered in 1807 by the Cornish inventor and chemist Humphry Davy. It occurs in sodium salts and minerals, including rock salt, sodalite, and feldspars.
