Chloride anion Cl- has the same electron configuration as Argon (its succeding noble gas) so:
Cl- has 18 electrons configured like: 1s2, 2s2 2p6, 3s23p6
Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
The chloride ion has an electron in plus.
The electron configuration of thaliium III ion is [XE] 4f14 5d10.
No. It is the other way around. The chloride ion has the extra electron.
The ions of elements nitrogen (N3-), oxygen (O2-), and fluorine (F-) will have the same electron configuration as a sodium ion (Na+), which is the same as the electron configuration of the noble gas neon.
The electron configuration of the chloride ion is: [Ne] 1s2.2s2.2p6.3s2.3p6.
Cl- Chloride ion 1s22s22p63s23p6 Cl Chlorine atom 1s22s22p63s23p5
Adding one electron gives the chloride ion which has an octet (it achieves the same electron configuration as argon.
chlorine have 17 atom the eletron configuration 1s22s22p63s23p5
Chlorine atom has 17 electrons. It is readily accepting an electron from another atom to obtain its stable electron configuration (of argon). A chloride ion has 18 electrons.
The electron configuration of selenium for a 2- ion is [Kr]4s2.3d10.4p6.
[Ne] 3s2 3p5 is the electronic configuration for neutral Chlorine. Its -1 ion, however is: [Ne] 3s2 3p6 or [Ar].
The chloride ion has an electron in plus.
which valance shell electron configuration of neutral atoms would represent an element most likely to form a 2-ion?
The element chlorine does not have noble gas configuration. But chloride ion formed (when chlorine accepts an electron) has noble gas configuration of argon.
It could be either Sn2+ ion (stannous ion) or Sn4+ ion (stannic ion)
It have an electron configuration of 2,8,8,SO it contains 8 electrons in it's outer shell.
