What do the quantum numbers of electrons represent? A. The total number of protons and electrons in the atom
B. The number of valence electrons the atom has
O C. The oxidation states most common to the atom
D. The energy levels and orbitals the electrons are in

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
