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 for H2O?
H2O is a molecule composed of two hydrogen atoms and one oxygen atom. Each hydrogen atom has an atomic number of 1, and the oxygen atom has an atomic number of 8. Therefore, the atomic number for H2O is 8.
What is the atomic number in O2?
The atomic number of an element refers to the number of protons in its nucleus. For oxygen (O), the atomic number is 8. So in O2 (oxygen molecule), each oxygen atom contributes its atomic number (8) to the total atomic number for the molecule.
Does carbon dioxide have a atomic number?
no. it is a combination of carbon and oxygen
What is the atomic number used for?
The atomic number of an element is the number of protons found in the nucleus of an atom. The atomic number is identical to the charge number of the nucleus. For example, the atomic number of Oxygen is 8.
What is the atomic number of H2O?
Atomic number is a property of an atom (An Element) and not a chemical compound. Water is a compound and thus it can not have any atomic number. Atomic number is the number of protons present in the nucleus of the atom of an element. e.g. Carbon has six protons in its nucleus, therefore its atomic number is six. However, sodium chloride has two different elements as its constituents and therefore one can not determine its atomic number.
What is the atomic number for the oxygen?
Oxygen has an atomic number of 8. This also means that it has 8 protons in its nucleus.
How many protons are ther in an atom of an oxygen?
Oxygen has 8 protons in the atom.
How many electrons in an atom with the atomic number 8?
An atom with atomic number 8 corresponds to oxygen. Oxygen has 8 electrons because the number of electrons in an atom is equal to its atomic number.
What is the atomic number of oxgyen?
The atomic number of oxygen is 8. This means that an oxygen atom has 8 protons in its nucleus.
What is the atomic number for H2O?
H2O is a molecule composed of two hydrogen atoms and one oxygen atom. Each hydrogen atom has an atomic number of 1, and the oxygen atom has an atomic number of 8. Therefore, the atomic number for H2O is 8.
How many electrons in an oxygen atom that has an atomic number of 8?
Every oxygen atom has eight electrons.
An electrically neutral atom of oxygen is likely to have this number of electrons?
Eight, the atomic number of oxygen.
What is the atomic number in O2?
The atomic number of an element refers to the number of protons in its nucleus. For oxygen (O), the atomic number is 8. So in O2 (oxygen molecule), each oxygen atom contributes its atomic number (8) to the total atomic number for the molecule.
What is the atom with atomic number 8 and mass number sixteen?
Atomic number 8 and mass number sixteen is Oxygen
The atomic number of oxygen means what?
The atomic number of oxygen, which is 8, represents the number of protons found in the nucleus of an oxygen atom. It determines the element's identity as oxygen and its placement on the periodic table. The atomic number also influences the chemical properties of oxygen.
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 many electrons are in oxygen atom that has an atomic number of 8?
Every oxygen atom has eight electrons.
