Cr [Ar] 4s^1 3d^5
The last electron in a copper atom has the quantum numbers n=3, l=2, ml=0, and ms=+1/2. The quantum numbers represent the energy level (n), sublevel (l), orbital orientation (ml), and electron spin (ms) of the electron, respectively.
n=4 l=0 m=0 s=-1/2
The last electron in gold is located in the 6s orbital. Therefore, the quantum numbers for this electron would be n=6 (principal quantum number), l=0 (azimuthal quantum number), ml=0 (magnetic quantum number), and ms=+1/2 (spin quantum number).
The last electron in cobalt has a quantum number of 3 for its principal quantum number (n), 4 for its azimuthal quantum number (l), -1 for its magnetic quantum number (m_l), and +1/2 for its spin quantum number (m_s).
n=4 l=2 ml= -1 ms= +1/2
Because a full 4s orbital is more stable than a full 3d and half full 4s. So, the last 3d electron jumps up to the 4s orbital.
The last electron in silver is in the 5s orbital. Silver has an electron configuration of [Kr] 4d^10 5s^1, indicating that the last electron is in the 5s orbital before entering the 4d subshell.
The last electron in gold is located in the 6s orbital. Therefore, the quantum numbers for this electron would be n=6 (principal quantum number), l=0 (azimuthal quantum number), ml=0 (magnetic quantum number), and ms=+1/2 (spin quantum number).
The last electron in cobalt has a quantum number of 3 for its principal quantum number (n), 4 for its azimuthal quantum number (l), -1 for its magnetic quantum number (m_l), and +1/2 for its spin quantum number (m_s).
The first three quantum numbers (principle, angular momentum, magnetic) are all whole numbers. The last quantum number (spin) is either ½ or -½.
Quantum numbers are a set of 4 imaginary numbers which explain the position and spin of electrons in an atom it can not explain an atom as a whole Iodine has 53 electrons so there are 53 sets of quantum numbers for Iodine.The above is correct. Assuming you meant to ask for the quantum numbers for the last electron added to Iodine, that would be n=5, l=1, m=0, s=1/2.
Copper as it had large amout of free electron in it.
Boron - 5e-1s^2 2s^2 2p^1n= 2l= 1ml= -1 -> 1ms= -1/2 , 1/2
n=4 l=2 ml= -1 ms= +1/2
Because a full 4s orbital is more stable than a full 3d and half full 4s. So, the last 3d electron jumps up to the 4s orbital.
The last year for copper US pennies was 1982.
