B. It allows scientists to predict things about objects that are too small to see.

Explanation:

Hello,

In science, we're always looking for the study of tinier things as long as we're interested about what the matter is made of. Several atomic models such as Bohr's, Rutherford's, Dalton's and the actual one have been proposed in order for us to understand how the protons, neutrons and electrons are assembled into the atom because they are too small to see (about 0.5 fm) thus, with that better understanding, we can research and develop novel applications for new materials based on the micromolecular behavior of the atom.

Best regards.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

im pretty sure its b
