After school, kai feels hungry and tired. he finds some sugar cookies in the cabinet and finishes the whole package. which statements best describe the role of glucagon and insulin in this scenario? glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. insulin was secreted after he ate the cookies because his blood glucose was high. insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. glucagon was secreted after he ate the cookies because his blood glucose was high. glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. after he ate, insulin from the cookies increased his blood sugar levels. insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. after he ate, glucagon from the cookies increased his blood sugar levels.

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.
