The (1st) ionization energy is the energy associated with the formation of 1 mole of negative ions from 1 mole (gaseous) atoms, and 1 mol of (gaseous) electrons.
Lunar synodic month ( 29.53 days) is longer than the sidereal month (27.32 days ). Synodic month is the period between two consecutive transits of the revolving-about-Sun heliocentric longitudinal plane...
This is one of the most important Periodic trends you can learn, in that it highlights the effects of periodicity. As $Z$, the increases sequentially, an electron is added to...
Electron affinity is the energy needed to add one electron to the atom, however, ionization energy is the energy needed to remove one electron from an atom. Electron affinity will...
Electronic configuration of atomic $Mg$: $1s^(2)2s^(2)2p^(6)3s^2$, versus $Al$, $1s^(2)2s^(2)2p^(6)3s^(2)3p^1$. Would you expect it to be easier to remove an electron from a $p$ orbital (with zero electron at the nucleus),...
Well, $"ionization energy"$ is the energy required for the formation of one mole of cations and one mole of electrons from one mole of starting element: $M(g)+Delta_"ionization energy"rarrM^(+)(g) + e^(-)$...
First ionization energy is for the electron removed from the neutral element, and second ionization energy is for the removal of the electron from the first ion generated due to...
Well, I would use to check these. I looked up the first two ionization energies (by typing the atomic symbol) and got... $"IE"_1 ("N") = "14.534 eV"" "" ""...
And we consider the ELEMENT not the molecule, inasmuch as this is how ionization enthalpies are defined...... $"Atom(g)"+Deltararr"Atom(g)"^+ + e^(-)$ For $Be$ we gots $Z=4$, $1s^(2)2s^(2)$ For $B$ we gots...
About $"1.89 eV"$ is released for the absorption, or absorbed for the emission process between $n = 3$ and $n = 2$. That means it takes about $1.89$ $"eV"$ of...
As a preface, since you have asked for the "difference in energy", I will give an answer that has no sign. That is, I will give $|DeltaE|$, a magnitude....
