Electronic configuration of sodium is : A. Sodium atoms have 11 For example, the atomic number of sodium is 11. Both atoms, which are in the alkali metal family, have only one electron in a valence s subshell outside a filled set of inner shells. Answer. Thus, electronic configuration of sodium is . Electronic configuration of Sodium. Atomic number of Na = 11 and electronic configuration is 1 s 2 2 s 2 2 p 6 3 s 1. These are referred to as the valence orbitals and the valence electrons. Electron Configuration and Oxidation States of Sodium. Electron Configurations The electron configuration describes how the electrons are distributed in the various atomic orbitals. The abbreviated electronic configuration of sodium: Na₁₁ = [Ne] 3s¹ . Write down the electron arrangement in a magnesium atom and a chlorine atom. Number of orbit in sodium = 3 . List two properties of the compounds formed by this bonding. Therefore, the electron configuration of the sodium ion is 1 s2 2 s2 2 p6. answr. Therefore, the electronic configuration of Sodium can also be written in a condensed form as [Ne] 3s ¹. Is the order of filling 1s 2p 3s 3p 4s 3d 4p 5s 6s 4f 5d 6p? 1; Poll Results. 28.57% (a) 2,8 ( 2 voters ) 14.29% (b) 8,2,1 ( 1 voter ) 0% (c) 2,1,8 57.14% (d) 2,8,1. The electronic configurations of most of the elements can be write in a simplified manner or condensed form. Upvote(1) How satisfied are you with the answer? sodium-2,8,1. MEDIUM. Following table gives condensed form for elements from Sodium to Potassium. Electron Configuration Asked by Topperlearning User | 21st May, 2014, 12:47: PM. Given the nature of the wave nature of electrons, he suggested that each negative particle is located on the "orbitals", that is, it has a certain spatial existence. Electronic configuration final 1. The electronic configuration of potassium is recorded according to the Pauli exclusion principle. The electronic configuration of sodium (2.8.1) shows that sodium, Na: is in period 3; is in group 1; has an atomic number. D. 1 s 2 2 s 2 2 p 6 3 s 1. Using this notation to compare the electron configurations of sodium and lithium, we have: Sodium: 1s 2 2s 2 2p 6 3s 1 = [Ne]3s 1: Lithium: 1s 2 2s 1 = [He]2s 1: It is readily apparent that both sodium and lithium have one s electron in their valence shell. Get Instant Solutions, 24x7 . pallaviv937 pallaviv937 Answer: lithium-2,1. 1s 2 2s 2 2p 6 Na+ has +1 positive charge and therefore it has lost an electron.It loses its one electron in its 3s orbital as that electron is at the highest energy - highest energy electrons are the first to be lost. Electron Configuration 2. Since, in a neutral molecule, the number of protons is equal to the number of electrons, we can also deduce that sodium also has eleven electrons. Thus, the electronic distribution of sodium ion will be 2,8. Sodium Complete Electron Configuration 1s2 2s2 2p6 3s1 Abbreviated Electron Configuration [Ne] 3s1 Sources Obtained by electrolysis of melted sodium chloride (salt), borax and cryolite. Write electronic configurations of sodium and chlorine and explain the formation of sodium chloride by electron-dot structure. 1 answer. This will help us to improve better. Write down the electronic configuration of magnesium atom and magnesium ion. Therefore we can say that sodium has eleven protons. Explanation of formation of sodium chloride : The atomic number of sodium is 11, so its electronic configuration is 2, 8, 1. In Aufbau Principle, the electrons are filled according to the increasing energy level of orbitals. The arrangement of electrons in the orbitals of an atom is called the electron configuration of the atom. No. Cl - = 2,8 An Ionic bond is formed between sodium ion and chloride ion by complete transfer of electron from sodium to chlorine. Electron Configuration Worksheet. 0 votes. Tag Archives: electron configuration of sodium. 0 votes. In order to achieve the nearest noble gas configuration, it gains one electron to form Chloride ion. toppr. 0 votes. of Mg = 12) asked Aug 13, 2019 in Class X Science by muskan15 (-3,443 points) metals and non-metals. The electron configuration of a neutral sodium atom is 1s^2 2s^2 2p^6 3s^1. As for the many-electron atom to which potassium belongs, there can be no more than two electrons on each orbitals. Sodium (Na) with an electron configuration of 1s 2 2s 2 2p 6 3s 1 sheds its outermost 3s electron and, as a result, the Na + ion has an electron configuration of 1s 2 2s 2 2p 6. So, a sodium ion has 11 – 1 = 10 electrons. While the unabbreviated electronic configuration is written without using noble gas electronic configuration. Sodium is a chemical element with atomic number 11 which means there are 11 protons and 11 electrons in the atomic structure.The chemical symbol for Sodium is Na. What changes take place in the electronic configurations of sodium and chlorine during the formation of sodium chloride? 1 answer. New questions in Chemistry. C. 1 s 2 2 s 2 2 p 7 3 s 1. According to the Aufbau Principle, first the atomic number of element is determined (like here oxygen has atomic … The atomic number of sodium is 11. Atoms prefer to gain the stability of octet, by having eight electrons in the outer shell, the electrons of the s and p orbitals. 1 answer. (b) Write the electron-dot structures for sodium and chlorine atoms. ( 4 voters ) Based On 7 Votes. Possible oxidation states are -1; +1.
