< Question 23 of 26 > An unknown metal sample with a mass of 14.8 g was obtained. The samp several metals are listed in the table. Metal Density (g/mL) aluminum 2.70 iron 7.87 cobalt 8.90 copper 8.96 gold 19.3 What is the possible identity of this metal sample?

b) mutualism

hope this : )

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

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: )
