Question

19) No currently known elements contain electrons in g (l = 4) orbitals in the ground

state.

If an element is discovered that has electrons in the g orbital,

a) What is the lowest value for n in which these g orbitals could exist?

b) What are the possible values of ml?

c) How many electrons could a set of g orbitals hold?

20) Describe the shielding effect and how it influences the attraction of a nucleus for outerlevel electrons.

21) Explain how the sizes of the atoms vary within the periods and groups of the periodic

table. In which part of the table are the elements with the smallest atoms found? In

which part of the table are the elements with the largest atoms found?

19. a) l for g-orbital = 4
Thur n = 1 , 2, 3 , 4 onwards
and 1=1 0- n-1 ( value range )
Hence when 1= $, lowest Possible in value = (+1 = 4+1 =5
.: Lowest Possible value of in with g-orbital n = s…
