Atom in the middle of a lewis structure

Postby Annabella_Amato_1I » Sat Nov 07, 2020 1:24 pm

When doing lewis structures, why is it that the atom with the lowest ionization energy goes in the middle?

The less energy that is needed for an atom to lose an electron, the greater the number of bonds that atom can participate in. Hope this helped :)

The atom with the lowest ionization energy has more space to accept electrons. Since low ionization energy corresponds with lower electronegativity, the nucleus does not have as strong a pulling power

Hi, it goes in the middle because it has the most open spaces to accept new bonds and electrons, so it is the most useful there.

Lower ionization energy (and thus lower electronegativity) has more space to accept bonds/electrons. So, it goes in the middle because this atom generally has the highest number of bonds in the atom

The atom with the lowest ionization energy goes in the middle of the lewis structure because they are more compatible to accept bonds and electrons with other atoms.

Atoms with lower ionization energy can create more bonds because they have fewer valence electrons.

Others have explained why the atom with the lowest ionization energy goes in the middle in that it tends to make the most bonds.

The logistics behind why the atom with the most bonds goes in the middle is because of convenience. Imagine if Lewis Structures were drawn that were centered on atoms that didn't make the most bonds. This would make the drawing awkwardly lopsided, as the drawing would perhaps only continue in one direction if an atom that only made one bond were the central focus.
