The octet rule states that elements tend to bond in such a way that each atom has eight electrons in its valence (outermost) shell, except for the first level which is complete with 2 electrons.
The first picture shows an atom with only 1 electron in its valence shell, the second picture 5 electrons, the third pictures 8 electrons and the fourth picture 2 electrons. The first and last cases are more likely to lose their valence electrons to form bonds than share them into a covalent bond (because they are few). The third case has the octet rule already satisfied, so is not likely to neither lose/receive nor share its electrons. The atom of the second case can share 3 electrons to complete the octet rule.
Ok look Im going try my best, and the answer that most likely looks like it can be correct is C the third picture i hope this is correct and helps bye bye:3
The most likely explanation for the sun looking like a cloud of hot steam is exploding from the surface is coronal mass ejections. The correct answer is C.
