Calculate the energy in calories required to produce, from neutral he atoms,1 mole of he+ ions and he++ ions using bohr's equations.

Explanation:

Energy necessary to remove an electron from outer orbital of a neutral gaseous atom or molecule is known as ionization energy.

Bohr's equation to calculate energy is as follows.

where,           = Reydberg's constant = per meter

In the given case, = 1 and =  

Therefore, calculate the energy as follows.

                            = J

                            = J

                            = J

As atomic configuration of helium is . Thus, energy required to produce and will be the same.

Also, 1 joule = 0.239 calories. Hence, convert calculated energy into joules as follows.

                          J

                         = cal

                          = cal

Therefore, we can conclude that cal energy is required to produce, from neutral He atoms,1 mole of ions and ions using Bohr's equations.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
