Give all possible ml values for orbitals that have each of the following: (a) l = 3; (b) n = 2; (c) n = 6, l = 1.

Respuesta :

Answer : All possible values of 'ml' for the following orbitals are:

(a) At l = 3,  [tex]m_l=+3,+2,+1,0,-1,-2,-3[/tex]

(b) l = 0, 1

At l = 0,  [tex]m_l=0[/tex]

At l = 1,  [tex]m_l=+1,0,-1[/tex]

(c) At l = 1,  [tex]m_l=+1,0,-1[/tex]

Explanation:

There are 4 quantum numbers :

Principle Quantum Numbers : It describes the size of the orbital. It is represented by n. n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

Magnetic Quantum Number : It describes the orientation of the orbitals. It is represented as m_l. The value of this quantum number ranges from [tex](-l\text{ to }+l)[/tex]. When l = 2, the value of [tex]m_l[/tex] will be -2, -1, 0, +1, +2.

Spin Quantum number : It describes the direction of electron spin. This is represented as [tex]m_s[/tex]The value of this is [tex]+\frac{1}{2}[/tex] for upward spin and [tex]-\frac{1}{2}[/tex] for downward spin.

(a) l = 3 then the value of 'ml' is,

At l = 3,  [tex]m_l=+3,+2,+1,0,-1,-2,-3[/tex]

(b) n = 2 then the value of 'ml' is,

l = 0, 1

At l = 0,  [tex]m_l=0[/tex]

At l = 1,  [tex]m_l=+1,0,-1[/tex]

(c) n = 6 and l = 1 then the value of 'ml' is,

n = 6

l = 0, 1, 2, 3, 4, 5

At l = 1,  [tex]m_l=+1,0,-1[/tex]

The  orbital refers to a region in space where there is a high probability of finding an electron.

What are orbitals?

The term orbital refers to a region in space where there is a high probability of finding an electron. Within each energy level, there are orbitals.

Let us consider each of the levels shown;

(a) l = 3

The ml values for this orbital are; -3, -2, -1, 0, 1, 2, 3

(b) n = 2

The ml values for this orbital are; -1, 0, 1

(c) n = 6, l = 1

The ml values for this orbital are; -1, 0, 1
