WebThe electronic structure of an atom can be predicted from its atomic number. For example, the atomic number of sodium is 11. Sodium atoms have 11 protons and so 11 electrons: … WebSodium has one valence electron. Valence electrons are electrons found in the outermost shell of an atom. Sodium (Na) is the eleventh element in the periodic table. It is an alkali metal that participates in the formation of bonds via one valence electron. Sodium configuration is 1s 2 2s 2 2p 6 3s 1. The last electron out of eleven goes to the ...

WebElectron affinity The energy released when an electron is added to the neutral atom and a negative ion is formed. Electronegativity (Pauling scale) The tendency of an atom to attract electrons towards itself, expressed on a relative scale. First ionisation energy The minimum energy required to remove an electron from a neutral atom in its ... WebOct 22, 2024 · The sodium atom has a total of 11 electrons, so we have to put 11 electrons in orbitals. The first two electrons will go in the 1s orbital as S orbital can hold a maximum of two electrons only. The next two will go in 2s orbital and the next six electrons will go in 2p orbital as P orbital can only hold a maximum of 6 electrons.
