What element has 8 protons 9 neutrons and 8 electrons?

Answer 1

The element with 8 protons, 9 neutrons, and 8 electrons is oxygen-17. Oxygen normally has 8 protons and 8 neutrons, but oxygen-17 is a rare isotope with an extra neutron. This gives it a total of 8 protons, 9 neutrons, and 8 electrons.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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

Answer 6

The element with 8 protons is oxygen. Adding 9 neutrons gives us an isotope of oxygen called oxygen-17. This isotope has the same number of electrons as protons, which is 8.

Answer 7

Oxygen-17, a very rare but stable isotype of oxygen.

Answer 8

The element with 9 protons is fluorine. In this case the isotope would be fluorine-17.

Answer 9

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. )

Answer 10

Oxygen is the element. It is a gas at room temperature. Atomic number of it is 8.
