The greater the number of electrons that travel in between the two atoms, the stronger the bond.
This can be due to an increased number of electrons or an increased speed.
However in ions (different number of electrons) this is not always the case and they can have a positive or a negative charge.
Hell, even if you do the calculations perfectly, they can still be incorrect, especially when you're with a high number of electrons.
Only a certain number of electrons, for example, could share a given energy level in an atom.
Such states exist as more number of electrons are pulled from their orbits.
The resulting material has a large number of free electrons.
Similar restrictions set the number of electrons in each orbit.
This limits the number of electrons in the same orbital to exactly two.
First assume that the total number of electrons is 4n + 2.
