17(2,8,7)
The electronic arrangement of chlorine is 2, 8, 7. This means that chlorine has 2 electrons in its first energy level, 8 electrons in its second energy level, and 7 electrons in its outermost energy level.
It goes form 2,8,7 to 2,8,8 as one electron has been gained in order to get a full outer shell and become more stable.
17(2,8,7)
Two electrons in the first level, 8 in the second, 7 in the third. The electron configuration notation is: 1s22s22p63s23p5, or [Ne]3s23p5. Incidentally, this is the same arrangement as in chlorine-37, which is chlorine's only other isotope.
Electronic configuration: - Chlorine: [Ne]3s23p5 - Fluorine: 1s22s22p5
A chlorine atom wouldn't need to lose anything, but a chlorine ion would need to lose 1
It goes form 2,8,7 to 2,8,8 as one electron has been gained in order to get a full outer shell and become more stable.
what does chlorine have t do to achieve the same electron arrangement as neon
Chlorine
17(2,8,7)
The electronic configuration of chlorine is 1s2, 2s2 2p6, 3s2 3p5.
Chlorine is diatomic but Sodium is not.
Chlorine
Two electrons in the first level, 8 in the second, 7 in the third. The electron configuration notation is: 1s22s22p63s23p5, or [Ne]3s23p5. Incidentally, this is the same arrangement as in chlorine-37, which is chlorine's only other isotope.
electronic configaration is the arrangement of electrons in an atom in different energy levels
Periodic table is an arrangement of elements. Chlorine is an element and hence it is there on the periodic table.
Argon
[Ne] 3s2 3p5 is the electronic configuration for neutral Chlorine. Its -1 ion, however is: [Ne] 3s2 3p6 or [Ar].
