Ca 4s23d9
Oxygen
There are 2 valence electrons in cerium
[Xe] Normally the electronic configuration for Barium would be [Xe] 6s2, but since you want it for Ba2+, you're missing two electrons. You get rid of the 6s2 and get [Xe].
[noble gas]nd1-10ns1-2
Iodine is a non metal element. Atomic number of it is 53.
The electronic configuration od Cu is [Ar] 3d10 4s1 This is an exception to the aufbau principle which would predict [Ar] 3d9 4s2.
The electron configuration of copper (Cu) is Ar 3d10 4s1.
The Cu orbital diagram is significant because it helps us understand the unique electronic configuration of copper. Copper's orbital diagram shows that it has a partially filled d orbital, which is unusual for an element in its group. This explains why copper can exhibit multiple oxidation states and form complex compounds.
what is the electronic configuration of the atomC6
The electronic configuration of tin is: [Kr]D10.5s2.5p2.
The electronic configuration of copper is Ar 3d10 4s1.
The electronic configuration of Bromine is [Ar] 3d10 4s2 4p5.
Electronic configuration means the arrangement of electrons in shells in atoms. Eg:Electronic configuration of Sodium is 1s2,2s2,2p6,3s1.
The electron configuration of Cu+1 is [Ar] 3d10 4s1. When copper loses one electron to become a +1 ion, it loses the 4s electron first, followed by one of the 3d electrons to attain a stable electron configuration.
Nb or niobium has the electron configuration of [Kr]4d45s1
Electronic configuration of scandium: [Ar]3d1.4s2
The electron configuration of polonium is: [Xe]6s24f145d106p4.
