The atomic weight (not mass) of oxygen is [15,99903; 15,99977] or in an abridged form 15,999.
The term Atomic Mass is used only for isotopes.
The mass number is the sum of neutrons and protons in an atomic nucleus.

What is the mass number for oxygen 18?
As the name would suggest, the mass of Oxygen-18 is 18.
What is the atomic number for the oxygen atom?
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16. The atomic weight of oxygen (not Atomic Mass) is [15,99903; 15,99977] after the IUPAC Tables - 2009. The atomic number of oxygen is 8.
What are the atomic number and mass number if the number of electron in an element oxygen is 8 and the number of neutrons is 9?
The atomic number is 8 (the number of protons, which for oxygen is equal to the number of electrons) and the mass number is 17 (the combined number of protons and neutrons).
Is the mass of a hydrogen atom different from the mass of an oxygen atom?
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
An oxide ion formed from an oxygen -18 atom contains exactly how many protons neutrons and electrons?
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.
What is the mass number of oxygen-8?
Oxygen is a non metallic element. Mass number of it is 16.
What is the mass number of oxygen 8?
No,the mass number of oxygen is 16 because it's atomic number is 8
What is the mass number of most atoms of oxygen?
Oxygen is a non metal element. Atomic mass number of it is 16.
What is the mass number for oxygen 18?

What is the mass number for O?
oxygen is a non metal element. Atomic number of it is 8.
He atomic number of oxygen is 8 What is the mass number of an oxygen atom with 7 neutrons?
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.
Why is 16 oxygen mass number?
Oxygen is a non metal element. Atomic mass of it is 16.
Was is the atomic mass number for oxygen?
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element.For example the isotope oxygen-16 has the mass number 16.The mass number is not the atomic mass !!
What is the atomic number and atomic mass for oxygen?
Oxygen is a non meta element. Atomic mass of it is 16 Atomic number of it is 8.
