Which statement describes the valence electrons in metallic bonds? a)they are shared equally between two atoms. b)they are shared unequally between two atoms. c)they are shared among many atoms. d)they are transferred from one atom to another.

Option (c) is the correct answer.

Explanation:

In metallic bonds, the valence electrons of interacting metal atoms from s and p orbitals are delocalized. Therefore, instead of revolving their respective metal atoms they form a sea of electrons.

Therefore, the positively charged atomic nuclei of the interacting metal ions gets surrounded by this sea of electrons.

Hence, we can conclude that the valence electrons in metallic bonds are shared among many atoms.

the answer to your question is c.

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.
