Electrons

How does spreading electrons further apart make the molecule more stable?

Electrons in an atom repel each other due to the fact that they have the same charge
The strength of repulsion is such that lone pair- lone pair repulsions > Lone pair - bond pair repulsions > bond pair - bond pair repulsions
Thus, by spreading the electrons and ensuring they're far away from each other, we reduce repulsions and thus make the atom/molecule more stable

Basically if the electrons were closer together they would want to repel, making them unstable, but if they are as far apart as possible they have nowhere to go, so they are stable.

Is this always true?

Yes, this is always true, as electrons will always be negatively charged and thus repel one another. Minimizing repulsion will always result in more stability.

atoms are more stable when electrons are as far apart as possible because there are less repulsive forces. This is always the case. Think about when you and your friend are pulling on something with all your strength. When one of you lets go the other goes flying. If there were less force pulling, there would be less flying off when the person lets go. It's a similar concept.

Thank you! This really made sense!

When electrons are close together, their negative charges repel each other which leads to a more unstable molecule. When the electrons are father apart, the electron electron repulsion is much less and in some cases 0.

Having the electrons the farthest apart means they are stable because they are equally repelling from the other elements, thus allowing little movement/instability.

Electrons naturally repel each other so having a greater distance between them would lower these repulsion forces.
