HELP PLS I NEED THIS BY THE END OF THE DAY I WILL GIVE BRAINLIEST Your friend says they bought a new ring with a ruby (corundum) in it for $2000 but you think they got cheated. You ask to borrow their pretty red ring and promise to give it back. It has a non-metallic, glassy luster. You test the ring and find that it scratches to glass but gets scratched by a piece of topaz you have. When you scratch it on an unglazed porcelain tile, you barely see a brown line. You tell your friend the bad news. What do they really have? Answer using claim, evidence, and reasoning.

fe 55.85 g/mol and h2o 18.02 g/mol.

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: )
