Let's say I want to determine what will happen during a chemical reaction. My current reasoning is that the electrons will be more likely to move from a less electronegative atom first. For instance, cesium is much more reactive than potassium, because its electronegativity is much lower, allowing it to give up electrons more easily. Is it this simple for any chemical reaction between complex molecules and simple atoms, or are there other key factors I should consider? Also, when determining what product a reaction will create, I am guessing that the most stable product will be the one that takes the least energy to make. As an example, if I decompose aluminum hydroxide (Al(OH)3), I believe it will be more likely to decompose into AlHO2 and water rather than aluminum metal, hydrogen gas, and oxygen gas, because it requires the movement of less electrons from the octet-satisfied oxygen ions. All I wish to know is if my understanding is correct, and if there is anything very important I need to know, please do correct me.
