Which of the following statements is true about the decomposition of a simple binary compound?
A. The products are unpredictable.
B. The reactants are the constituent elements.
C. The reactant is a single substance.
D. The product could be an ionic or a molecular compound.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

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: )
