Two scientists, Tara and Victor, work in the same scientific field of study. Victor asks Tara to review a research paper that he wrote to determine if it should be published. After replication, Tara suggests that Victor’s paper should not be published and that he should perform his experiment again. What would be the most likely reason she suggests Victor perform his experiment before publication?

Tara does not think that Victor’s predictions are likely.

Tara does not think that Victor’s conclusions are important.

Tara does not get the same results when she conducts the experiment.

Tara does not find other research papers that published similar information

Tara does not think that Victor’s predictions are likely.

Explanation:

In order to submit the paper, he would need to be as accurate as he possible can, is Tara told him to do it again, it means that he may have made a few mistakes.

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.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
