WebThe octet on each atom then consists of two electrons from each three-electron bond, plus the two electrons of the covalent bond, plus one lone pair of non-bonding electrons. ... (Since there is no 1p subshell, 1s is followed immediately by 2s, and thus shell 1 can only have at most 2 valence electrons). Hydrogen only needs one additional ... WebAnd you have one more electron to worry about. And so that electron would go into a 3S orbital. So the full electron configuration is 1S2, 2S2, 2P6, and 3S1. When I want to figure out how many valence electrons sodium has, the number of valence electrons would be equal to the number of electrons in the outermost shell, the outermost energy level.

WebHow many shells are there? There are 4 subshells, s, p, d, and f. Each subshell can hold a different number of electrons.Search form. Shell Subshell Total Number of Electrons in Shell 1st Shell 1s 2 2nd Shell 2s, 2p 2 + 6 = 8 3rd Shell 3s, 3p, 3d 2 + 6 + 10 = 18 4th Shell 4s, 4p, 4d, 4f 2 + 6 + 10 + 14 = 32 WebFeb 19, 2014 · The first shell can carry up to two electrons, the second shell can carry up to eight electrons. The third shell can carry up 18 electrons, but it is more stable by carrying … WebThe second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further grouped into subshells of four different types, identified as s, p, d, and f in order of increasing energy.
