A balloon filled with helium gas at 1.00 atm occupies 14.0 L. What volume would the balloon occupy in the upper atmosphere, at a pressure of 0.22 atm and a constant temperature?
Enter your answer in the box provided.
L

explanation: no but i do not usually comment

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: )
