Which of the following is true of all stars? A) they produce energy and radiation B) they have about the same temperature c) they are generally the same size and color D) they produce energy for the same length of time​

A)

Explanation:

All stars produce some type of energy and radiation. But stars vary in temperature, size, color, and the length of energy they produce.

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: )
