Unlike protons and neutrons, which consist of smaller, simpler particles, … WebbMolecules, in turn, are composed of atoms joined by chemical bonds that are more difficult to break. Each individual atom consists of smaller particles--namely, electrons and nuclei. These particles are electrically charged, and the electric forces on the charge are responsible for holding the atom together.
WebbProtons are smaller than a neutron or an electron. Neutrons are smaller than a proton or an electron. Electrons are smaller than a proton or a neutron. Protons and neutrons have similar mass. Electrons are smaller than a proton or a neutron. WebbIn transient experiments, where the inhibiting adsorbates are allowed to desorb, smaller 1.7 nm Rh particles and larger 3.7 nm Rh particles reach similar rates of CO activation despite the steady-state TOF being an order of magnitude higher on the larger particles.
