Lauren benson: when electrons gain energy they more away from the nucleus, when electrons loose energy try fall back to a shell close to the nucleus. Vi) electron distribution: the behavior or an element usually depend on the number of electrons in its outermost shell called valence electrons, the outermost electron shell called the valence shell. Xi) weak helical bonds: weak bonds are a crucial part of cell function for they occur within a larger covalent bond, hydrogen bonds. Xii) hydrogen bonds: when a hydrogen is covalently bonded to an electronegative atom while attracted to another, h2o, nh3. Xv) chemical reaction is the making and breaking of bonds: reactant is what is being changed, product is what is left or made from the change, reactions cannot destroy matter, it can only rearrange it. Xvi) photosynthesis: 6co2+6h2o c6h12o6 + 6o2, sunlight powers the conversion of raw materials (carbon and oxygen, etc) into glucose.
