COBALT ELECTRON CONFIGURATION FULL

So, again, I'm going to make this argon just make it for myself 4s1, 3d10 and again you might see it as argon 3d10, 4s1 same exact thing. That way this d orbital or d sublevel be completely filled which is very stable versus the s orbital will be halfway filled. Okay so anytime that it ends in d9 we're going to fix it up a little bit, same exact way we're going to take an electron from the 4s and we're going to move it over to the 3d. So let's make the electron configuration for that 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d9 from here on out anytime you see d9 we're going to change it. So you might see either one but they're the same.ĭown here the other exception that you're going to see is copper, or anything along copper which we'll talk about. So this is talking about the order of energy you might see it also looking like this, this is just doing it in order of number 3 comes before 4 but they're exactly the same thing, they're depicting the exact same thing, nothing different about them. You might see this is the diagram or the electron configuration that you're going to see and this is actually higher in energy than this. So instead we're going to write actually we're going to make this argon as we noted before in the noble gas configuration and we're going to make this 4s1, 3d5 this is halfway filled which is pretty stable and this is much more stable being half way filled rather than being the d4. So what we're going to do, we're going to, that should be a 2 there, sorry, and we're going to take one of the electrons in the 4s orbital and move it over to the 3d orbital. Right now we're 1 electron short of it being halfway filled.

The d sublevel is more stable when its either half full all the orbitals are filled with at least 1 electron or completely filled. If we're going to make this short hand and make the electron configuration for this we would make this 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d4 okay from now on every time you see 3d4 you're going to change it, we do not like 3d4. Chromium is a transition metal and it has 24 electrons and here is the orbital diagram. When the atom is in excited state, one or more electrons go to a higher energy state, so electron configuration of the excited atom is different.Okay alright so let's talk about the exceptions you're going to see when you're dealing with electron configuration there's going to be a few around but we're going to talk about the main ones you're probably going to see in class. the state in which all electrons have the lowest possible energy. The electron configuration of the chemical element describes the ground state, i.e.Visually we say that the electron configuration determines the distribution of electrons on the shells and subshells. The electron configuration shows in which states individual electrons are located in atom.For this reason, electrons in atoms take on successive states starting from the one with the lowest energy. in a state described by all identical quantum numbers. According to Pauli's principle, in the atom there can not be 2 electrons in an identical quantum state, i.e.Specifies an additional, internal moment of momentum of the electron, which has no equivalent in classical physics. the so-called spin quantum number s, takes values -1/2 or +1/2.Specifies the number of the orbital angular momentum projection on the selected axis, the so-called magnetic quantum number m, takes integer values -l.Specifies the subshell number to which the electron is assigned and its orbital moment of momentum. the so-called azimuthal quantum number l, takes the integer values 0,1,2., n-1.Specifies the energy number of the electron and assigns electron shell. the so-called principal quantum number n, takes natural values 1,2,3.The atomic orbital depends parametrically on few variables:.If we think about electon inside chemical molecule, we say about molecular orbital. In the case of electrons in a single atom, we say about atomic orbital. The function describing the state of a single electron is called orbital.

The quantum state of an electron is described by a mathematical function called wave function.
