. The energy of shells in a hydrogen atom is calculated by the formula E = -Eo/n^2 where n is any integer, and Eo = 2.179X10^-18 J. So, the energy of a ground state electron in hydrogen is:

E = -2.179X10^-18 J / 1^2 = -2.179X10^-21 kJ

Consequently, to ionize this electron would require the input of 2.179X10^-21 kJ


2. The wavelength of a photon with this energy would be:

Energy = hc/wavelength

wavelength = hc/energy

wavelength = 6.626X10^-34 Js (2.998X10^8 m/s) / 2.179X10^-18 J = 9.116X10^-8 m

Converting to nanometers gives: 91.16 nm


3. Repeat the calculation in 1, but using n=5.


4. Repeat the calculation in 2 using the energy calculated in 3.

Answer:

The value of ionization energy is 8.716\times 10^{-23} kJ.

Explanation:

E_n=-13.6\times \frac{Z^2}{n^2}eV

where,

E_n = energy of n^{th} orbit

n = number of orbit

Z = atomic number

We are given: Z = 1 , n= 5

E_5=-13.6\times \frac{1^2}{5^2}eV=-0.544 eV

Z = 1 , n = ∞

E_{\infty }=-13.6\times \frac{1^2}{(\infty )^2}}eV=0 eV

Ionization energy to ionize the hydrogen atom where electron is present in n=5 initially will equal to the difference between energy of electron at infinity from the energy of electron at n = 5 energy level.

I.E=E_{\infty }-E_5

=0 eV-(-0.544 eV)=0.544 eV

1 eV= 1.60218\times 10^{-22} kJ

0.544 eV=0.544\times 1.60218\times 10^{-22} J=8.716\times 10^{-23} kJ

The value of ionization energy is 8.716\times 10^{-23} kJ.

HeeeeeeeeeeeelllllllllllllllllllllllpppppppppppppppppppppppppppppFind the statement about Fusion that is false.
Pie

Fusion releases less energy than fission

fusion most commonly combines heavy isotopes of hydrogen into helium.

Explanation:

Nuclear fusion is a form of reaction that involves the combination of two light nuclei to form one that is heavier in mass.

The other form is nuclear fission which is the splitting of heavier nuclei either spontaneously or when bombarded with other nuclei.

  • Nuclear fusion reactions in the core of stars powers the universe.
  • The reactions produces a huge amount of energy of a greater and massive order than fission reaction.
  • Small nuclei are involved in nuclear fusion and not the large ones.
  • Nuclear fusion degenerates into series of chain reactions that are extremely difficult to control.
