carbon-14
Oxygen has an atomic mass of 8 and typically has 8 neutrons.
The element that has 8 protons and 8 neutrons is oxygen.
The element with 6 protons and 8 neutrons is carbon-14, which is a radioactive isotope of carbon.
Oxygen is the only element with 8 protons.
The number of neutrons in an element can be determined by subtracting the atomic number (number of protons) from the atomic mass number (which is the sum of protons and neutrons). For an element with an atomic mass of 16, if we consider the most common isotope of oxygen (which has an atomic number of 8), it would have 16 - 8 = 8 neutrons. Thus, the element with an atomic mass of 16 typically has 8 neutrons.
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.
The element with 8 protons and 8 electrons is oxygen (O). The presence of 11 neutrons indicates a specific isotope of oxygen, oxygen-19.
The element with 6 neutrons and 8 other neutrons is carbon. Carbon-12 is the most common isotope of carbon, with 6 protons and 6 neutrons. Carbon-14 is another isotope of carbon, with 6 protons and 8 neutrons.
Phosphorus and sulfur both have 16 neutrons.
The symbolic notation of this element would be ^18O, where 18 is the sum of the protons and neutrons in the nucleus, O represents the element oxygen.
Isotopes of the same element have different number of neutrons.
