Explanation / Answer

a) the maximum number of electrons in the 4th energy levele is : 32e-

explanation : 4th energy level contains s,p,d ,f and g orbitals. these orbitals containig 2,6,10,14 and 18 respectively

b) the maximum number of electrons in the f sub level : 14e-

c) the number of orbitals in the d sub level is = 5

explanation : "d" orbital contain 10 electrons in 5 sub levels with 2 electrons each

d) the maximum number of electrons in ONE 2p orbital = 6 electrons

e) the number of orbitals in the 2nd energy level :- two orbitals

i.e the second shell have 2s orbital ans 2p orbital

f) the number of orbitals when = 3 is

explanaton:

g) what are the possible values of when n=5?

ans: range of values between 0< <n-1

hence n=5, vlaues are 0,1,2,3,4(s,p,d,f,g orbitals)

h) when =1 , what are the values of m =?

ans: m is magnetic quantum number between -<m<

hence   =1, m = -1,0,1

i) when   =2, the sublevel is designated with the letter :- "d" orbital

explantion : because m is magnetic quantum number between -<m<

hence   =2, m = -2,-1,0,1,2

j) the maximum number of electrons with the quantum numbers n=3,   =2 , m = -1,ms = +1/2

Ans: the given data representing 3d orbital and it containg only one electron

k) an electron with qunatum numbers n=7,   =0 , m = 0,ms = +1/2 is representing 7s Orbital

l) what is the number of d orbitals with n=2 ?

, the orbital angular momentum qunatum number defines the subshell. this quantum number defines the shape of the orbitals and the values of "" are integers dependent on the values of "n" .    = 0,1,2,......,n-1

hence n=2,   values are -2,-1,0,1,2

so, the number of d orbitals when n=2 are 5.

m) how many electrons can have the qunatum numbers n=3 and m =0?

ans: if the value of n=3 the   values are -3, -2,-1,0,1,2,3

if m =0, it representing 3d orbital and containing two electrons

n) which quantum number (n , ,  m , ms) indicates the orientation of orbital?

ans: m , the magnetic quantum number defines the orientation of the orbital in space.
