What element has atomic mass of 16 and 8 neutrons?
The element with an atomic mass of 16 and 8 neutrons is oxygen. Oxygen has 8 protons in its nucleus, giving it an atomic number of 8. By subtracting the number of protons from the atomic mass, we can determine the number of neutrons, which is 8 in this case.
What is the approximate mass of an oxygen atom in atomic mass units?
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
How do you get the mass number of an atom?
Look on the Periodic Table. The bottim number is the Atomic Mass and the top is the atomic number. ex. The atomic mass for O (oxygen) is 16.
What the mass number oxygen?
Oxygen is a non metal element. Atomic mass of it is 16.
Do carbon and oxygen have the same atomic mass?
No, carbon and oxygen do not have the same atomic mass. Carbon has an atomic mass of approximately 12 atomic mass units, while oxygen has an atomic mass of approximately 16 atomic mass units.
