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.

Is the atomic mass of oxygen 16?
Oxygen is a non meta element. Atomic mass of it is 16.
What is the mass of one mole of Al2O3 if aluminum has an atomic number of 13 and an atomic mass of 26.98 and oxygen has an atomic number of 8 and an atomic mass of 16.00?
The mass of one mile of a compound is found by adding up the atomic masses of each of the component elements. A mole of Al2O3 has mass of 2 × 26.98 + 3 × 16.00 = 101.96g
What element has atomic mass 16.00?
Oxygen has an atomic mass of approximately 16.
What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why is the atomic mass number not a whole number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
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.
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 is the atomic number and the mass number of oxygen?
The atomic number of oxygen is 8, which means it has 8 protons in its nucleus. The mass number of oxygen is approximately 16, which accounts for the total number of protons and neutrons in its nucleus.
What are the atomic and mass numbers of 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 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 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 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.
What is the atomic number and weight for oxygen?
The atomic number of oxygen is 8, which represents the number of protons in the nucleus. The atomic weight of oxygen is approximately 16.00 atomic mass units, which is the average mass of an oxygen atom taking into account its isotopes.
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.
What is the atomic number and mass of Oxygen-17?
The atomic number of Oxygen is 8, indicating the number of protons in its nucleus. Oxygen-17 has 8 protons and 9 neutrons, giving it a mass number of 17.
What is the atomic symbol and atomic mass of 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 atomic weight of oxygen (not atomic mass) is [15,99903; 15,99977] after the IUPAC Tables - 2009. The atomic number of oxygen is 8. The chemical symbol is O.
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 is the atomic mass mass number of oxygen?
The atomic mass number of oxygen is 16.0. --------- 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. After IUPAC Tables from 2009 the atomic weight of oxygen is [15,99903; 15,99977]. The conventional (abridged) atomic weight is 15.999 amu.
