Elements that form ionic bonds generally have how many valence electrons?

they should have a number that can completely transfer and fill the other atom

Explanation:

example:

sodium(2.8.1)and Chlorine(2.8.7)the sodium will give chlorine the 1 valence electrobo so they both become stable(2.8)±and(2.8.8)–

magnesium(2.8.2)and oxygen(2.6)same way as above to abtain mg(2.8)±²and oxygen(2.8)–²

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )
