E Which is one piece of information that "9" gives about
an atom of fluorine?
The atomic mass is different than the atomic number,
and the number of neutrons is the difference between
the atomic mass and the atomic number.
O the atomic number
O the atomic mass
o the hiass of protons
o the number of neutrons

The information in that "9" is the atomic number of the atom.

Step-by-step explanation:

For an atom of fluorine we have:

A = atomic weight = 18.99 amu.

Z = atomic number = 9.

(A - Z) = number of netrons = 10.

Then the "9" in the information of the atom of fluorine gives information about the atomic number.
