The energy required to ionize boron is 801 kJ/mol. You may want to reference (Pages 93 - 98) Section 2.5 while completing this problem. Part A What minimum frequency of light is required to ionize boron

The frequency is  

Explanation:

From the question we are told that

   The energy required to ionize boron is

Generally the ionization energy of boron pre atom is mathematically represented as

Here   is the Avogadro's constant with value

So

=>    

Generally the energy required to liberate one electron from an atom is equivalent to the ionization energy per atom and this mathematically represented as

=>    

Here h is the Planks constant with value

So

=>      

what's the question?
