a)A N6+ ion in its ground state absorbs an X-ray photon of energy 2.0000
keV. Explain what happens to the ion and why.
b)Explain why the nitrogen ion N6+ is a hydrogen-like ion. Assuming the
ion is for the major stable isotope 14N, state which sub-atomic particles
it contains and how many of each there are in the N6+ ion.
a. Upon absorbing the 2 keV, an electron, we will call it the outermost one, will move to an outer orbit.
b. N^6+ is a nucleus plus 1 electron. The H atom is a nucleus plus 1 electron. The N^6+ ion has 1 electron in the outer shells, there are 7 protons in the nucleus and 7 neutrons also.
Hi, With that amount of energy the electron will not only move to a higher orbit but move into the continuum, severing its link with the nucleus.
Work out the energy of ionisation and check the 2000 eV difference.

a) When a N6+ ion in its ground state absorbs an X-ray photon of energy 2.0000 keV, one of its electrons is excited to a higher energy level. The absorbed energy promotes the electron from its ground state to an excited state further from the nucleus. This process is called electronic excitation.
The N6+ ion has 7 electrons in total (6 removed electrons and the remaining valence electron). The energy of the absorbed X-ray photon matches the energy difference between the ground state and the excited state of the valence electron. As a result, the electron moves to a higher energy level and the N6+ ion becomes an N5+ ion.
b) The nitrogen ion N6+ is considered a hydrogen-like ion because it has the same electronic structure as hydrogen. In a hydrogen-like ion, there is one electron orbiting around the nucleus, similar to the hydrogen atom.
For the N6+ ion, since nitrogen has an atomic number of 7, it normally has 7 electrons. However, the N6+ ion indicates that 6 electrons have been removed, leaving only 1 valence electron. This ion contains one proton in its nucleus, which gives it a positive charge of +6, attracting the remaining electron.
In summary, the N6+ ion contains one electron and one proton. The electron orbits around the nucleus, similar to how an electron in a hydrogen atom would orbit around its nucleus.
a) When a N6+ ion in its ground state absorbs an X-ray photon of energy 2.0000 keV, it undergoes a transition from its lower energy state to a higher energy state. This absorption of energy promotes one of the outer shell electrons to a higher energy level. This electron gets excited and jumps to a higher energy shell, leaving behind a vacancy in the lower energy shell.
The X-ray photon energy required to excite the N6+ ion corresponds to the energy difference between the ground state and the higher energy state. This energy difference is specific to each atom or ion and is determined by the electron configuration and atomic structure of the species.
b) The nitrogen ion N6+ is considered a hydrogen-like ion because it has a strong similarity in its electronic structure to that of a hydrogen atom. In a nitrogen atom, there are seven protons, seven neutrons, and seven electrons. In the N6+ ion, which has lost six electrons, the number of protons and neutrons remains the same. Thus, the N6+ ion has seven protons and seven neutrons.
Since the N6+ ion has lost six electrons, it means it only has one electron remaining. This electron occupies the lowest energy level (shell) closest to the nucleus. Similarly to the hydrogen atom, the N6+ ion has only one electron outside its fully filled inner shells.
Therefore, the N6+ ion, which is the nitrogen ion with a charge of +6, can be referred to as a hydrogen-like ion due to its electronic structure and the fact that it has only one electron remaining.
