What are the 4 quantum numbers for calcium?
Its electron configuration is: 2 electrons in the K shell (principal quantum number 1), 8 in the L shell (principal quantum number 2), 8 in the M shell (principal quantum number 3), and 2 in the N shell (principal quantum number 4).
What are the 4 quantum numbers of chlorine 17?
– The electronic configuration of the chlorine is [Ne]3s23p5 . – Therefore the quantum numbers for chlorine are principal quantum number (n) is 3, azimuthal quantum number (l) = 1 for 3p –orbital, magnetic quantum number (m) is -1, 0 , 1 and spin quantum (s) number is either −12or+12 .
What is the 17th electron?
How to Write the Electron Configuration for Chlorine (Cl) In order to write the Chlorine electron configuration we first need to know the number of electrons for the Cl atom (there are 17 electrons).

Calcium/Electron configuration
What are the four quantum numbers of the last electron added to FE?
For iron, [Ar]4s23d6 , then n=3 , l=2 (because it is the d orbital), ml is −2 (because you count up one the series from −l to +l six times, for the six electrons in the d subshell) and ms is ±12 .
What is the spin quantum number of CA?
In this case, the fact that calcium is located in group 2 tells you that it has 2 valence electrons. The first valence electron is added to the 4s orbital when the orbital is empty, so we assign it a positive spin, or m2=+12 .
Which quantum number is different for the valence electrons of calcium?
4s
Valence electrons are located in the outermost shell, the shell with the highest principle quantum number. For calcium, the outermost shell is 4s. The value that corresponds to 4s is .
What is the quantum number of the 17th electron in calcium?
Counting along we find that the 17th electron resides in the p subshell of the 3rd shell, so has principal quantum number n equal to 3 and angular momentum quantum number l equal to 1 The electron arrangement of calcium is 2,8,8,2.
How many quantum numbers are there in an atom?
The 4 quantum numbers: In atoms, there are a total of 4 quantum numbers: the principal quantum number (n), the angular momentum quantum number (l), the magnetic quantum number (ml), and the electron spin quantum number (ms). Principal quantum number (n): The principal quantum number describes the electron shell, or energy level, of an electron.
How do you find the last valence electron in a calcium atom?
Identify the 4 quantum numbers for the last valence electron in a Calcium atom. Step 1: Find Calcium on the Periodic Table. It has an atomic number of 20. Step 2: Find the n and l values. Since Calcium is an S-block element, its n value is the same as the period n = 4 and l = 0 .
How many valence electrons does calcium have in Group 2?
In this case, the fact that calcium is located in group 2 tells you that it has 2 valence electrons. The first valence electron is added to the 4s orbital when the orbital is empty, so we assign it a positive spin, or m2 = + 1 2. This implies that the second valence electron that is added to the 4s orbital will have a negative spin, ms = − 1 2.
