Question 2 of 10 Which of the following best describes technology?
A. The method of thinking that scientists use.
B. The application of engineering to create useful products.
C. Something created for only scientists to use.
D. A scientific idea.

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: )
