What component of atoms was discovered by rutherford?

The component of atom discovered by Rutherford is protons.

According to his gold foil experiment, where he bombarded alpha-particles on gold foil he discovered a positive charge center in the atom. The concentrated center has most of the mass of the atom. The positive center was introduced as nucleus containing positive charged particles, protons.

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!
