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 is the oxygen mass number?
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.
If the atomic mass of oxygen?
Oxygen is a metal element. Atomic mass of it is 16.
What the atomic mass in oxygen?
Oxygen is a non metal element. Atomic mass of it is 16.
What is the atomic mass of an oxygen atom?
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
Why do atomic mass numbers have decimals for oxygen?
The mass number is the sum of protons and neutrons in the atomic nucleus of chemical elements. All mass numbers are integers. The atomic weight is not an an integer because is calculated taking in the account the isotopic composition of an element; also the mass excess has a role.
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.
Oxygen has eight protons eight neutrons and eight electrons what is the atomic mass?
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.
What is the atomic mass of o?
The Atomic Mass of Oxygen is: 15.999
Is the atomic mass of oxygen 16?
Oxygen is a non meta element. Atomic mass of it is 16.
What is the empirical formula of a compound that contains 57 percent sulfur and 43 percent oxygen by mass?
Since the atomic mass of sulfur is very close to twice the atomic mass of oxygen, the ratio of numbers of oxygen atoms to numbers of oxygen atoms is close to 43:28.5. The closest ratio of small integers is 3:2; therefore the empirical formula is S2O3.
What is the relative formula mass of oxygen?
Oxygen is a non meta element. Atomic mass of it is 16.
What is the atomic mass of oxygen-15?
The atomic mass of oxygen-15 is 15. The atomic mass consists of protons and neutons, and oxygen-15 has 8 protons and 7 neutrons.
