What did J. J. Thomson’s experiments with cathode ray tubes imply about the mass of an electron? Electrons are many thousand times larger than the nucleus and negatively charged.
Electrons are many thousand times smaller than the nucleus and positively charged.
Electrons are many thousand times smaller than the nucleus and negatively charged.
Electrons are many thousand times larger than the nucleus and possess no charge.

c Electrons are many thousand times smaller than the nucleus and negatively charged.

Explanation:

trust me slime

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!
