A laser light was shone through a diffraction grating whose lines were 1/1000 mm apart. The distance was measured between the ce

nter spot and the first side spot and found to be 99 mm. The distance from the dif‐ fraction grating to the first side spot was found to be 154 mm. Calculate the wavelength of light in nm that the laser pointer was emitting

What is meant by the ground state of an atom? What is meant by the ground state of an atom? All of the quantum numbers have thei
ANTONII [103]

Answer: Option (a) is the correct answer.

Explanation:

We know that ground state means in total electrons acquired by the element are present in their lowest energy level.

We calculate the azimutal numbers as follows.

                      n = l + 1

where,     n = principle quantum number  

                l = azimuthal quantum number

Values of n can be 1, 2, 3, 4 and so on. Whereas the values of l can be 0, 1, 2, 3, and so on.

Also, "m" is known as magnetic quantum number whose values can be equal to -l and +l.  

So, when n = 1 then l = 0 and m = 0.

When n = 2 then l = 1 and values of m will be equal to -1, 0, +1. As it is given that the magnetic quantum number ml = -1. Hence, it is only possible when n = 2.

And, n = 1 is the lowest energy level. Therefore, we can conclude that the ground state of an atom means all of the quantum numbers have their lowest values (n = 1,ℓ = mℓ = 0).
