Answer:
The value is
Explanation:
From the question we are told that
The wavelength is
The velocity is
The mass of electron is
Generally the energy of the incident light is mathematically represented as
Here c is the speed of light with value
h is the Planck constant with value
So
=>
Generally the kinetic energy is mathematically represented as
=>
=>
Generally the ionization energy is mathematically represented as
=>
Answer:
The energy of an electron in an isolated atom depends on b. n only.
Explanation:
The quantum number n, known as the principal quantum number represents the relative overall energy of each orbital.
The sets of orbitals with the same n value are often referred to as an electron shell, in an isolated atom all electrons in a subshell have exactly the same level of energy.
The principal quantum number comes from the solution of the Schrödinger wave equation, which describes energy in eigenstates , and for the case of an hydrogen atom we have:
Thus for each value of n we can describe the orbital and the energy corresponding to each electron on such orbital.
