How many orbitals are contained in the fourth shell in modern quantum mechanics

Question

How many orbitals are contained in the fourth shell in modern quantum mechanics (n-4) of a given atom? Which of the following set of 3 quantum numbers describes a 4t orbital? n = 2, l = 1, ml = -2 n = 2, l = 0, ml = 0 n = 4, l = 3, ml = -2 n = 3, l = 1, ml = 0 n = 1, l = 0, ml = 0 Which of the following statements is TRUE? The principal quantum number (n) describes the dupe of an orbital. The angular momentum quantum number (l) describes the the size and energy associated with an orbital. An orbital is the path that an electron follows during its movement m an atom. The magnetic quantum number (ml) describes the orientation of the orbital. All of the above are true. Sketch one of the 3p orbitals below. How are they different from the 2p orbitals?

Explanation / Answer

6. 4f

n= 4 , l=3   ml= -3,-2,-1,0,+1,+2,+3

C. n= 4, l=3, ml = -2

7. D

magnetic quantum number describe orientation of orbital.

8. 3p

   n= 3 l=1 shape is dumble               

2p

n= 2 , l= 1 shape is dumble
