Which two subatomic particles have the same mass but do not have the same charge? A. None of these
B. Neutrons and quarks
C. Electrons and neutrons
D. Protons and neutrons

d

Explanation:

b/ce The strong force effects produce a mass that is essentially independent of the kinds of quarks involved, so this mass contribution will be the same for the proton and neutron.

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!
