How Many Protons, Neutrons, and Electrons in an Atom?
WebSince 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining electron in the 3s. Therefore the sodium electron configuration will be 1s 2 2s 2 2p 6 3s 1. WebOct 22, 2024 · The electron configuration of neutral Na is 1s22s22p63s1 but in Na+ it loses one electron, so it has a new electron configuration of 1s22s22p6 means Na+ has (2+6=8) outermost electrons which makes it stable. Thus, sodium ion … WebThe N shell containing 4s, 4d, 4p and 4f, can carry 32 electrons. Such an arrangement helps explain the periodicity and periodic trends observed across the elements of the periodic table. Subshell Configurations … chlamys hastata
