what are the four quantum numbers for the last electron in for cr3+?
605703
The correct quantum numbers for the last electron in Chromium: $Cr = [Ar] 3d^{5} 4s^{1}$ Thus n =3, l = 2, m = +2, s = +1/2 Also, if these same quantum numbers are used, it is the same with the last quantum number of manganese.

When we write the configuration we'll put all 24 electrons in orbitals around the nucleus of the Chromium atom. NOTE: Chromium is an exception to the rules for writing electron configurations! In writing the electron configuration for Chromium the first two electrons will go in the 1s orbital.

Since according to this rule the electrons are filled in the 1s, 2s, 2p, 3s, 3p, 4s, 3d, … order, the 19th electron is occupying 4s orbital. The corresponding quantum number is n=4, l=0, and may be +1/2, -1/2 or both at same time (see Quantum superposition - Wikipedia).

To completely describe an electron in an atom, four quantum numbers are needed: energy (n), angular momentum (ℓ), magnetic moment (mℓ), and spin (ms). The first quantum number describes the electron shell, or energy level, of an atom.

The answer is 8 valence electrons. The valence electrons are those in the outermost shell, i.e. theshell with the highest principal quantum number n.

This element is found in group 5 and period 4. The electron configuration is 1s2 2s2 2p6 3s2 3p6 s2 3d3. This means that it tells us that the atomic number is 23 and it tells use the number of valence electrons.

They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). (Like the other elements in Group 1, hydrogen (H) has one electron in its outermost shell, but it is not classed as an alkali metal since it is not a metal but a gas at room temperature.)

There are four quantum numbers: n, ℓ, mℓ, and ms. Each one is a particular factor in an equation describing a property of the electron. At this introductory level, the equations are not needed. The value of each quantum number is assigned to each electron in an atom by a "building up" process.

The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.
