Manganese atom has 30 neutrons and atomic number 25 determine the electron cloud charge of manganese

the most common oxidation no.of manganese is +2 +3 +4 +6 +7

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.

i'm pretty sure its b i might be wrong though!
