1. The Atomic Mass of oxygen is [15,99903; 15,99977].
2. The mass number is the sum between the number of neutrons and protons in the atomic nucleus and this value is specific for each isotope of a chemical element.
For the isotope 16O the mass number is 16.
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
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.
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
The mass number =18
Atomic number 8 and mass number sixteen is Oxygen
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.
Yes. The element with an atomic number of 8 is oxygen and it's average atomic mass is 15.9994 (rounded to 16).
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
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.
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
The number of neutrons in an atom can affect the atomic mass of an 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.
No, the atomic mass number is the number of protons plus the number of neutrons. The atomic mass of an atom is the total mass in a motionless atom.
mass no - atomic no = number of neutrons in an atom.
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
The mass number =18
