it has 8 protons and 10 neutrons and 8 electrons
Protons & electrons 8
Neutrons 10.
Electrons = 8
Neutrons = 10
8 protons, 8 electrons and 10 neutrons

O-18 atom has 8 protons, 8 electrons and 10 neutrons.
The mass number =18
Oxygen-18 has 8 electrons and protons; the number of neutrons is 10.
There are several. However, Chlorine is one. Chlorine-35 has 17 protons, 18 neutrons and 17 electrons in its isotopic atom. However, Chlorine-37 has 17 protons, 20 neutrons and 17 electrons in its isotopic atom.
Because the world is made up like this. Well, a 18O, as it's name shows, has a releatve mass of 18 units. A proton has got a mass of 1 ,a neutron ahd got a mass of 1, and electron has gor a amss of 1/1840 (we dont calculate with a this small mass). So in a 18 relative mass, neutrons + protons = 18. As oxygen is the 8th in the periodic table, it has got 8 atoms. So neutrons + 8 = 18, where neutrons = 10.
In the nucleus of an oxygen-18 atom there are 10 neutrons while in the nucleus of an oxygen-16 atom there are only 8 neutrons. The number of electrons and protons always stay the same.
2 extra neutrons
write the anatomic symbol for isotopes with the an oygen atom with 10 neutrons
The isotope oxygen-18 has the mass number of 18. The atomic number of oxygen is 8, so all of its atoms, regardless of isotope, have 8 protons. In a neutral oxygen atom the number of protons equals the number of electrons, so it has 8 electrons. The number of neutrons equals the mass number minus the atomic number, which for oxygen-18 is (18 - 8), so there are 10 neutrons.
O-18 atom has 8 protons, 8 electrons and 10 neutrons.

Oxygen-18 has 8 electrons and protons; the number of neutrons is 10.
The simple answer is 8 neutrons. But this depends on which oxygen isotope you are talking about. Oxygen-16, the most abundant oxygen isotope, has 8 neutrons.
