Sara and Greg built an electromagnet in science class . They wrapped 50 turns of copper wire around an iron nail and Hooke the ends of the wire to a 1.5 volts battery . They picked up 15 paper clips with their electromagnet , but they want to make it stronger . What should they do

lol for the pointsss

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: )
