Within each group of four atoms or ions presented below, select the species that are isoelectronic with each other: zn, fe3+, mn2+, ar, ge2+, cl-, b-, c

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.

it's c (engineer's do their work with mechanical stuff not on any living being)
