Consider the statement: “The following report presents the results of our laboratory tests, which support the conclusion that our new
treatment for acne is safe and effective with minimal possible side effects."

What questions should a person ask themselves to determine if this scientific study is reliable?

O What does the acne medicine look like?
O What does the acne medicine smell like?
O Were laboratory tests conducted by the same company that produces the acne medicine?
O Were laboratory tests conducted in a laboratory with more than 100 employees?

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.

lol idk man i guess u gotta ask bill nye the science guy

its first and third is your answer i did the qustion the fourth isnt right
