Giving a specific number of protons and neutrons specifies an isotope of an element. In this case, the isotope is the isotope of fluorine with an Atomic Mass of 19. Other isotopes of fluorine with different numbers of neutrons also exist, but are not nearly as common.
The only thing you really need to know is the "9 protons" part. That would be fluorine.
---------------------------------
Fluorine. Fluorine has an atomic number of 9 and therefore has 9 protons. In the isotope fluorine-18 it has 9 neutrons. There is only a trace of this in nature, the most common isotope is fluorine-19 with 10 neutrons
--------------------------------------------------------------------
An element is always determined by number of protons it has in an atom, therefore, a 9-proton atom belongs to Fluorine(F) which is the most electronegative and reactive of all elements.
-----------------------------------------
Oxygen is the element. It is a gas at room temperature. Atomic number of it is 8.
Eight protons denote that the atomic number is 8. Nine neutrons imply that its atomic mass is (9+8)=17. Therefore, the atom is oxygen-17.
The answer is Fluorine. This is becuase, even though it only has 9 neutrons instead of it's normal 10,this doesn't really change the element, only what isotope it is.So in other words,the answer is Fluorine-18
Oxygen-17, a very rare but stable isotype of oxygen.
The element with 9 protons is fluorine. In this case the isotope would be fluorine-17.
8 17 This isotope of oxygen has 8 protons (atomic number), 8 electrons and 9 neutrons. (Recallthat mass number is the total of protons and neutrons. )

The element that has 8 protons and 8 neutrons is oxygen.
8 protons, 8 neutrons and 8 electrons.
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons. Isotopes of the same element have the same number of protons and electrons, which is the atomic number of the element.

8 protons 8 electrons and 8 neutrons. Oxygen has the atomic number 8, so it has 8 protons, 8 electrons. The number of neutrons would be mass number-atomic number, so 15.9994-8=7.9994, so rounding would be 8 neutrons.
5 protons 8 neutrons try it

The element that has 8 protons and 8 neutrons is oxygen.
Just add the protons and the neutrons. The answer is 14.
8 protons, 8 neutrons and 8 electrons.
There are 8 neutrons in oxygen element because the no. of electrons are equal to the number of protons and oxygen element contain 8 electrons.
The isotope of oxygen, 8O17
The isotope boron-11 has 5 protons and 6 neutrons, but also 5 electrons not 8.
Oxygen because its atomic number is eight
The pair below that describes isotopes of the same element is B, an atom with 6 protons and 6 neutrons-an atom with 6 protons. It is not A, an atom with 6 protons and 8 neutrons- an atom with 8 protons and 6 neutrons.
