The age of water or wine may be determined by measuring its radioactive tritium content. Tritium is formed via cosmic radiation of water in the upper atmosphere, and decays spontaneously by a first order process with a half-life of 12.5 years. Suppose that a wine vendor sells a certain wine for which he desires a premium price. The tritium content of this wine is found to be only 10 % as radioactive as a new bottled specimen.

did anyone actually do this? like if anyone has submitted this i rly need .

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: )
