What is the element whose d sublevel is filled and its highest energy electron has the set of quantum numbers: n=4, l=0, ml=0, ms=+1/2
So this should have an electron structure of
1s2 2s2 2p6 3s2 3p6 3d10 4s1 which makes it Cu.
To determine the element with the given set of quantum numbers, we need to understand the meaning of each quantum number.
The principal quantum number (n) represents the energy level or shell of an electron. In this case, n=4, indicating that the electron is in the fourth energy level.
The azimuthal quantum number (l) describes the shape of the electron orbitals within a given energy level. It can have values ranging from 0 to (n-1). Here, l=0, meaning that the electron is in an s orbital.
The magnetic quantum number (ml) specifies the orientation of the orbital in three-dimensional space. For an s orbital, the only possible value of ml is 0.
Finally, the spin quantum number (ms) indicates the spin state of an electron. It can have two possible values: +1/2 (spin up) or -1/2 (spin down). In this case, ms=+1/2, indicating that the electron has spin up.
Now, to find the element with these quantum numbers, we need to know the electron configuration of elements. The electron configuration of an element describes the distribution of electrons in the various atomic orbitals.
Since the d sublevel is filled in this case, it means that all the orbitals with the quantum number l=2 are already occupied. Therefore, the element is located in either the third or fourth row of the periodic table, as these are the rows where the d orbitals become available.
Considering that the highest energy electron is in the n=4 energy level, we can conclude that the element belongs to the fourth row of the periodic table, also known as the row of transition metals.
To identify the specific element, we need more information, such as the total number of electrons in the atom. With that information, we can construct the electron configuration and identify the element based on the position in the periodic table.
