Dos átomos con una diferencia de electronegatividad de 0.4 forman un enlace que es iónico, porque los electrones se transfieren

covalente, porque los electrones se comparten

iónico, porque los electrones se comparten

covalente, porque los electrones se transfieren

lol for the pointsss

i don,t know so just answer mine

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: )
