What is the identity of the atom shown? A). Fluorine
B). Neon
C).nitrogen
D).potassium

Option A

Explanation:

The answer to this question is the first option or "fluorine." You can find the amount of protons, neutrons, and electrons by looking at the elements atomic number and mass number. In this case we have the first option fluorine which it's atomic number is nine which is why the element has nine protons, and electrons, and nine neutrons because of it's mass number.

Hope this helps.

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!
