The outermost energy shell of an atom, containing the valence electrons involved in the chemical reactions of that atom. orbital. The three-dimensional space where an electron is found 90% of the time. outermost. How an atom behaves chemically mostly depends on the number of electrons in the atom's ____________ shell.
Types of Chemical Reactions. Doing chemical reactions is the main focus of chemistry because that's where the action is. That's when something gets made, changed, or destroyed. So a lot of emphasis is placed on chemical reactions. Chemical reactions can be understood by these three areas of focus. A reaction is basically shuffling around the building blocks of chemistry (atoms/ions/molecules/electrons). Force & energy is what decides if the reaction occurs and how fast.
