The binary representation is : 1111011001
The abbrieviated electron configuration of copper is [Ar] 4s23d9
[Ar] 4s2 3d9
The actual for copper is 3d10 4s1. 3d10 4s2 is Zinc. 3d8 4s2 is Nickel. Among these Transition Metals [in this book], 3d9 4s2 is not listed. Help pls.
The electron configuration of copper(II) is [Ar] 3d9 . Copper is [Ar] 3d10 4s1
chromium (Cr) and copper (Cu)chromium has 4s1,3d5 instead of 4s2,3d4 and copper has 4s1,3d10 instead of 4s2, 3d9
The electron configuration of a Copper(II)ion is [Ar]4s0 3d9.
Because having a half-filled s sublevel, such as 4s1, followed by a filled d sublevel, such as 3d10 is more stable than having a filled s sublevel, such as 4s2, followed by a d sublevel that is almost full, such as 3d9, which is very unstable.
The electronic configuration od Cu is [Ar] 3d10 4s1 This is an exception to the aufbau principle which would predict [Ar] 3d9 4s2.
The electronic configuration of copper is 2)8)8)2 as the atomic number is 20.Mass no.is 40 and it has 20 neutrons.But, the orbital electronic cofiguration of copper is: 1s2 2s2 2p6 3s2 3p6 4s1 3d10
Cobalt has 9 valence electrons and generally cant lose 9 electrons to achieve the noble gas configuration.
