Atoms have a positive nucleus, a core of protons balled up a bit like our sun, while clouds of negative electrons orbit the nucleus similar to planets (well, more like asteroid belts) orbiting the sun. The charges of an atom add up evenly to make the atom energy neutral when it exists alone in a vacuum. Neutral does not mean stable, though. Stability on an atomic level comes from satisfaction within the electron clouds.
Most humans are also a mix of positive and negative emotional charges and are vulnerable to giving or receiving negativity in interactions with other people in an attempt to find satisfaction and stability. A rare few are so internally stable that no matter what is going on around them, they don’t transfer negativity and in fact bring those around them relief and protection from emotional volatility.
Expose most atoms to other atoms and they react to one degree or another over time, because most atoms are vulnerable to either losing or gaining electrons. A small number of atom types are so internally balanced that they never lose or gain negativity except in the rarest, most exceptional circumstances and are often used to insulate other elements from the environment.
Balance and stability requires the equalization of opposing forces. It is not about the eradication of negativity, it is about accepting the presence of negativity and finding ways to counterweight it.
Chemical reactivity comes from a lack, from empty spots in the outside layer of the electron clouds surrounding every atom. Atoms lacking enough electrons, enough negative energy, desperately seek to change that imbalance. The magic number is eight, with few exceptions, and elements just shy of 8 electrons in their peripheral energy cloud will grab onto the nearest negativity to fill themselves up. While elements with few electrons in the outer shell will give them away to drop down to the lower energy level for stability.
People either try to elevate or lift themselves up to the next energy level or drop themselves down to the one below. They use people and things around them, either boosting themselves, or boosting others.
