Looks like seven valance electrons to me. that would make this group the halogens, 7A.
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5 or [Ne] 3s2 3p5 in shorter notation.
Short: [Ne] 3s2 3p5 Long: 1s2 2s2 2p6 3s2 3p5
[Ne] 3s1 3p5
Chlorine's atomic number is 17. Thus, neutral chlorine has 17 protons and 17 electrons. Its total configuration is 1s2 2s2 2p6 3s2 3p5, so its valence configuration is 3s2 3p5.
Chlorine is a non-metal. It is found in group 7 of the periodic table of elements and has electronic configuration [Ne] 3s2 3p5.
Because it is missing the electronic configuration for 2p orbital.
The electronic configuration of chlorine is 1s2, 2s2 2p6, 3s2 3p5.
The electronic configuration of chlorine is [Ne] 3s2 3p5 or 2, 8, 7
[Ne] 3s2 3p5 is the electronic configuration for neutral Chlorine. Its -1 ion, however is: [Ne] 3s2 3p6 or [Ar].
Chlorine is a non-metal. It is found in group 7 of the Periodic Table of elements and has electronic configuration [Ne] 3s2 3p5.
Chlorine is a non-metal. It is found in group 7 of the Periodic Table of elements and has electronic configuration [Ne] 3s2 3p5.
6. Electronic configuration, 1s2 2s2 2p6, 3s2, 3p5
[Ne] 3s2 3p5 is the electronic configuration for neutral Chlorine. Its -1 ion, however is: [Ne] 3s2 3p6 or [Ar].
yes F is smaller than Cl due to their electronic configuration. electronic configuration of F is 1s2, 2s2, 2p5 electronic configuration of Cl is 1s2, 2s2, 2p6, 3s2, 3p5
The electron configuration of the element chlorine (atomic number 17) is : 1s2 2s2 2p6 3s2 3p5 In noble gas form : [Ne]3s23p5
Chlorine is the group 17, period 3 chemical element. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p5. Another way to write this is [Ne] 3s2 3p5 since the beginning of the electron configuration is the same as neon's.
The electron configuration for chlorine is 1s2 2s2 2p6 3s2 3p5 or [Ne] 3s2 3p5 in shorter notation.
