Webelectron shell, regions surrounding the atomic nucleus containing a specific number of electrons. Each allowed electron orbit is assigned a quantum number n that runs from 1 (for the orbit closest to the nucleus) to infinity (for orbits very far from the nucleus). All the orbitals that have the same value of n make up a shell. Inside each shell there are … WebWith 11 electrons how many electron shells does sodium have? 3 4 2 1. Answers: 2 Show answers .

Why does the atomic radius increase as you go from the top to the bottom of a chemical familyone proton has a greater effect than one electron11. Think and discuss: Compare the electron configurations of hydrogen, lithium, and sodium. Webeight electrons occupy the second shell; one electron occupies the third shell; This electronic structure can be written as 2,8,1 (each comma, or dot, separates one shell from … novarics ltd israel

WebSodium atoms have 11 protons and so 11 electrons: two electrons occupy the first shell eight electrons occupy the second shell one electron occupies the third shell This electronic... WebIn this sense the third shell can hold 8 electrons. 4s2 not the third shell, but the next 10 electrons go into the 3d orbitals that are part of the third shell but shown on the fourth shell level. … So the third shell can be considered to hold 8 or 18 electrons but in total the third shell can hold 18 electrons. Web2.Carbon is in Group 4A, so it has 4 valence electrons. 3.Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. novaria holdings llc houston
