Question:
Give the chemical symbol for the element with the ground state electron configuration [Ar]4s^23d^3
Answer:
Answer No 1:
The chemical symbol for the element with the ground state electron configuration [Ar]4s23d3 is ‘V’.
Explanation:
The total electrons present in Argon [Ar] are 18.
So, there are total (18+2+3)=23 electrons present in the [Ar]4s23d3 electron configuration.
Therefore, 23 is the Atomic number of ‘Vanadium’ whose chemical symbol is ‘V’.
Answer No.2:
For 4s : n=4
For 4s : l = 0
Explanation:
In the question ‘n’ is called ‘Principal Quantum Number‘ , ‘l’ is called ‘Azimuthal Quantum Number’ .
1. Principal Quantum Number(n):
It determines the energy of an electron in an orbit where electron is present.
For 4s ,the value of the principal quantum number (n) is 4.
2. Azimuthal Quantum Number(l):
It determines the number of subshells to which the electrons belong.
The value of l = (n-1) always where n is the number of principle Quantum Number.
For 4s, the value of ‘l’ is 0.
Answer no.3
The possible values of ml for the 4s subshell is ‘0’.
Explanation:
Magnetic Quantum Number(ml):
It gives the number of permitted orientations of orbitals.
The value of ‘ml‘ varies from ‘-l’ to ‘+l’ through zero.
In the question , for 4s, the value of ‘l’ is 0. So the value of Magnetic Quantum Number(ml) is 0.
Answer no.4:
For 3d : n = 3
For 3d : l = 2
Explanation:
In the question ‘n’ is called ‘Principal Quantum Number’ , ‘l’ is called ‘Azimuthal Quantum Number’ .
1. Principal Quantum Number(n):
It determines the energy of an electron in an orbit where electron is present.
For 3d ,the value of the principal quantum number (n) is 3.
2. Azimuthal Quantum Number(l):
It determines the number of subshells to which the electrons belong.
The value of l = (n-1) always where n is the number of principle Quantum Number.
For 3d, the value of ‘l’ is 2.
Answer no.5:
The possible values of ml for the 3d subshell are ‘-2,-1,0,+1,+2‘.
Explanation:
Magnetic Quantum Number(ml):
It gives the number of permitted orientations of orbitals.
The value of ‘ml‘ varies from ‘-l’ to ‘+l’ through zero.
In the question , for 3d, the value of ‘l’ is 2. So the value of Magnetic Quantum Number(ml) is ‘-2,-1,0,+1,+2’.
