The <em>effective nuclear charge</em> is the difference between the atomic number an element and the shielding constant. Hence, the atom which experiences the greatest nuclear charge is Sulphur, S.
<u>Calculating the greatest effective nuclear charge</u>, :
- Z = Atomic number ; S = shielding constant
<u>For Magnesium, Mg</u>:
Z = 12
S = 10
<u>For Aluminium, Al</u>:
Z = 13
S = 10
For Sulphur, , S:
Z = 16
S = 10
Therefore, the atom whuch experience the greatest
is Sulphur.

Sin(30°) =1/2 0.5
cos(30°) = (√3)/2
Note that the sin of an angle is equal to the cos of the complementary angle:
sin(60°) =cos(30°) = (√3)/2 since 30+60 = 90 (compl. angle)
