At the middle school level, it is not necessary for students to learn about electron orbitals. This information is offered so that it is clearer to you why electrons are often shown in pairs in energy ...

An energy-level diagram of an oxide/organic interface is illustrated in Fig. 1a. The relevant parameters of energy-level alignment, such as oxide work function (), ...

It can be represented on an energy level diagram. The diagram shows that when a catalyst is used, the activation energy is reduced. This makes more of the collisions successful at a given temperature.
