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 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.
Why is oxygen's atomic number 8?
Each oxygen atom contains 8 protons in its nucleus. The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.
6 The atomic number of oxygen is 8 because oxygen has?
The atomic number of oxygen is 8 because oxygen has 8 protons in its nucleus.The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.The Atomic Number is a count of how many Protons are present in an atom of an element.The element Oxygen has 8 Protons in its atomic nucleus and therefore has an Atomic Number of 8.Note: in an electrically neutral atom the number of electrons in the electron cloud exactly matches the number of Protons in the nucleus of the atom, therefore electrically neutral oxygen will also have 8 electrons.
When the nucleus of a nitrogen atom absorbs a proton the resulting element is?
Oxygen, the element with an atomic number higher by one than that of nitrogen.
What are the chemical symbols for the elements carbon aluminum hydrogen oxygen and sodium?
oxygen atomic number 8 symbol O. carbon atomic number 6 symbol C, hydrogen atomic number 1 symbol H. nitrogen atomic number 7 symbol N.
How many protons are ther in an atom of an oxygen?
Oxygen has 8 protons in the atom.
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 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 one thing that determines the identity of an atom that is whether it is an oxygen atom or a carbon atom?
The number of protons in the nucleus of an atom determines its identity as a particular element. The number of protons is the element's atomic number, and is unique to each element. For example, the atomic number of oxygen is 8, while the atomic number of carbon is 6.
What is the atom with atomic number 8 and mass number sixteen?
Atomic number 8 and mass number sixteen is Oxygen
How many electrons are in oxygen atom that has an atomic number of 8?
Every oxygen atom has eight electrons.
What is the number of neutrons in elements of the periodic table?
you take the atomic mass of an atom say, 16 for oxygen, and subtract the atomic number, 8 for oxygen. 16-8= 8. so there are eight neutrons in the typical oxygen atom.
If an atom had an atomic number of 8 and has an atomic mass of 19 is the atom considered an isotope?
Yes. The element with an atomic number of 8 is oxygen and it's average atomic mass is 15.9994 (rounded to 16).
How do you account for the number of protons?
The atomic number of an element accounts for the number of protons in the nucleus of the atom of that element. For example: * Hydrogen atomic number is one. The nucleus of its atom has one proton. * Oxygen atomic number is 8. The nucleus of its atom has 8 protons. * Iron atomic number is 26. The nucleus of its atom has 26 protons. * Lead atomic number is 82. The nucleus of its atom has 82 protons. * Uranium atomic number is 92. The nucleus of its atom has 92 protons.
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 only thing that determines in the identity of the act come that is whether it is in oxygen atom or a carbon atom?
The atomic number of an element determines how many protons are in the nucleus and therefore how many electrons are in a neutral atom of the element. The atomic number of oxygen is 8 and the carbon atom is 6.
