Aluminum (atomic number 13), with 13 electrons and the electron configuration [Ne]3s 2 3p 1, is analogous to its family member boron, [He]2s 2 2p 1. There are 118 elements in the periodic table. The number of valence electrons in the atom is . The electronic configuration of magnesium atom is 1s2 2s2 2p6 3s2. What is the electron configuration for a magnesium ion, Mg? This document is highly rated by Class 9 students and has been viewed 2345 times. 1s2 2s2 2p6 3s1 1s2 2s2 2p6 3s2 1s2 2s2 2p6 1s2 2s2 2p6 3s2 3p1 None Of The Above Could You Explain Also? What atom matches this electron configuration? https://www.periodic-table.org/magnesium-configuration-oxidation 1s 2 2s 2 2p 6 3s 1. This problem has been solved! For magnesium, Z=12..... And so we simply use the aufbau scheme: 1s^(2)2s^(2)2p^(6)3s^2..... What is the electronic configuration of Mg^(2+)? Using the electronic configurations, explain how magnesium atom combines with oxygen atom to form magnesium oxide by transfer of electrons. 3. Potassium. where as in magnesium ions the electronic configuration is 1s2 2s2 2p6 which attains Neon configuration. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure. metals and non-metals class-10 See the answer. Electron Configuration Chart for All Elements in the Periodic Table. Tags: Question 14 . The electron configuration of a neutral magnesium atom is: 1s2 2s2 2p6 3s2 or in shorthand [Ne] 3s2. Your first guess of B would be right if you were taking Magnesium at its ground state. For example, lithium forms Li +, with the 1s 2 configuration, magnesium forms Mg 2+, with the 2s 2 2p 6 configuration for its highest energy electrons, and chlorine forms Cl-, with the 3s 2 3p 6 configuration. 8. Q. Magnesium. Mg+2 is an ion that loses two electrons from its highest energy level, 3s. Therefore, you're left with 2p6 3s0 or just 2p6. 10. Tags: Question 2 .
