the element that has 8 neutrons is Oxygen
If you had looked in the periodic table, you would have seen that the element Oxygen has an atomic mass of 16 (or more precisely 15.9994) and if you were to take that atomic mass and subtract the atomic number from it (i.e. 8) you would get a difference of 8 which is the number of neutrons it contains. In short, oxygen is that element.
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
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. Therefore, atomic mass of oxygen is 15.
There is no element with an atomic number of 12 and an atomic mass of 8. Atomic number corresponds to the number of protons in an atom, while atomic mass is the sum of protons and neutrons. The atomic number of an element cannot be smaller than its atomic mass.

The element that has 8 protons and 8 neutrons is oxygen.
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.

No, the atomic number refers to the protons of an atom, and for the most part the electrons. The atomic mass refers to the neutrons of an element in a way; the atomic mass consists of protons and neutrons, so if you subtract the amount of protons from the atomic mass, you get the amount of neutrons. For example oxygen has an average atomic mass of 16.01 and has 8 protons, so 16.01 atomic mass-8 protons=8.01 average neutrons. Now this is just for the average amount of neutrons, which is changed by isotopes (atoms with different amounts of neutrons).
There are 8 neutrons in oxygen. You can determine the number of neutrons in any element by subtracting the atomic number (which is 8 for oxygen) from the atomic mass, rounded to the nearest whole number (which is 16 for oxygen). This is because the mass of any element comes mainly from the protons and the neutrons - the mass of the electrons is too tiny to be a significant contribution. The atomic number corresponds to the number of protons in an element, so when you subtract it from the element's total mass, you are left with the number of neutrons.
Oxygen is a pure element. It's element 8 on the periodic table. 8 protons, 8 electrons, 8 neutrons. Atomic mass is about 16 amu (atomic mass units)
The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element. The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number. Take for example, oxygen. Oxygen has an atomic number of 8 and a mass number of 16. Hence, from the atomic number it can be derived that it has: 8 electrons 8 protons While from the mass number, it can be derive that it has: 16-8 = 8 neutrons
you use the mass number for the neutrons. you take away the atomic nomber from the mass number and the answer is the number of neutrons. for the electrons and the protons you just write the atomic number.
