ASAP! two different atoms have nine protons each and the same mass. However one is neutral while the other has a negative charge. Describe what each atomic structure could be, listing the possible number and location of all subatomic particles.

Two different atoms have 9 number of protons.

One atom is neutral atom that means it has 9 number of electrons.

One atom has a positive charge that means it has 8 number of electrons.

The atom will be fluorine (F) because it has the 9 number of protons.

And the atomic mass of fluorine is 19.

As per given question, both the atoms have the same mass that means both the atoms has 10 number of neutrons.

Number of neutrons = Atomic mass - Atomic number = 19 - 9 = 10 neutrons

Therefore, the two different atoms could be, _9F and _9F^+ and the location of all subatomic particles is that the protons and neutrons are present in the nucleus and the electrons are present around the nucleus.

i wish i could but this one is weird give me abc and i can solve it.
