The atomic diameter is typically 1 x 10-10 m, and the atomic nucleus has a width of 1 x 10-14 m. Imagining scaling these sizes to everyday objects. If a tennis ball (diameter = 6.50 cm) represented the nucleus, how wide would the atom be?

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!
