The energy required to ionize magnesium is 738 kj/mol. what minimum frequency of light is required to ionize magnesium

The minimum frequency required to ionize the photon is 111.31 × Hertz

Given:

Energy = 378

To find:

Minimum frequency of light required to ionize magnesium = ?

Formula used:

The energy of photon of light is given by,

E = h v

Where E = Energy of magnesium

h = planks constant

v = minimum frequency of photon

Solution:

The energy of photon of light is given by,

E = h v

Where E = Energy of magnesium

h = planks constant

v = minimum frequency of photon

738 × = 6.63 × × v

v = 111.31 × Hertz

The minimum frequency required to ionize the photon is 111.31 × Hertz

Explanation:

Relation between energy and frequency is as follows.

                     E =

where,   E = energy

              h = planck's constant = Js

          = frequency

As it is given that value of energy is 738 kJ/mol.

          E =

             = J

Hence, putting the given values into the above formula as follows.

                      E =

    J =  

                    = per second

Thus, we can conclude that per second is the minimum frequency of light which is required to ionize magnesium.

coil wire, increase current, put iron inside the coil

answer: good job it's all correct !
