Which of the following gives the correct possible
values of/ for n = 4?
o 0, 1, 2, 3
-4, -3, -2,-1,0, 1, 2, 3, 4
o 0, 1, 2, 3, 4

l= 0, 1, 2, 3

m= -3, -2, -1, 0, 1, 2, 3

s= +1/2 or -1/2

Explanation:

The principal quantum number is denoted by n and which gives the size of the atomic orbital. It is given an integer value (e.g., n = 1, 2, 3...), and its value is never 0.The angular momentum quantum number/azimuthal quantum number describes the shape of the atomic orbital. l can take values from 0 to n-1.The magnetic quantum number, m distinguishes the orbitals available within a sub-shell. It can take values from -l to l including 0.The Spin Quantum Number s gives the angular momentum of an electron.  Because angular momentum is a vector, the Spin Quantum Number (s) has both a magnitude (1/2) and direction (+ or -). So, it can be -1/2 or +1/2.

For the given value of n=4

l= 0, 1, 2, 3

m= -3, -2, -1, 0, 1, 2, 3

s= +1/2 or -1/2

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
