WHAT TYPE OF WAVE IS SHOWN? (view picture) A) Transverse Wave
B) Longitudinal Wave
C) Combined Wave
D) Sound Wave

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.
