The radius of a cadmium atom is approximately 0.16 nm. What is the magnitude of the ionization energy? (in joules)
Step 1: Using Bohr's radius equation, we know that:
r = (0.529*10^-10)*n^2/Z
Given that radius of cadmium atom is 0.16 nm, So
r = 0.16*10^-9 m = 1.6*10^-10 m
So,
1.6*10^-10 = 0.529*10^-10*(n^2/Z)
n^2/Z = 1.6/0.529
Step 2: Now magnitude of ionization energy of atoms is given by:
E = 13.6 eV*(Z^2/n^2)
1 eV = 1.6*10^-19 J
Z = atomic number of Cadmium = 48
So,
E = 13.6*1.6*10^-19*Z*(Z/n^2)
E = 13.6*1.6*10^-19*48*(0.529/1.6)
E = 3.45*10^-17 J = Magnitude of ionization energy
Let me know if you've any query.
