Oxygen has 8 protons . The number of neutrons depends on the isotope. Oxygen-15 isotope has 7 neutrons and oxygen-16 isotope has 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
The atomic number of oxygen is 8, which means that there are 8 protons in the nucleus of an oxygen atom. Mass number = protons + neutrons, therefore neutrons = mass number - protons = 16 - 8 = 8 neutrons.
Oxygen has 8 electrons and protons. The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - Number of protons
Oxygen has 8 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in an oxygen isotope = Mass number - 8
eight
There are 8 neutrons in oxygen. In order to get number of neutrons, you will subtract the number of protons which is 8 from the atomic mass weight of oxygen which is 16.
The atomic mass of oxygen (8 protons + 7 neutrons) is 15.For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n.p = no. of protons.n = no. of neutrons.
The difference between Oxygen - 15 and Oxygen - 16 is that of Isotope. Oxygen's atomic number is 8 as it contains 8 proton but the neutron number may vary in order to form an isotope, the oxygen found in the air is 98 percent oxygen 16, the rest is oxygen 15. Oxygen 16 = 8 protons, 8 neutrons, 8 electrons. 16 is the mass number which is equal to the (number of proton + number of neutrons) Oxygen 15 = 8 protons, 7 neutrons, 8 electrons. 15 is the mass number which is equal to the (number of proton + number of neutrons) Oxygen 15 is known as the "Isotope" of Oxygen 16.
Oxygen has 8 neutrons. However, there are other isotopes that have a different number than this.
other gases
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.
