There ain't no such animal ! Oxygen is a gas with an atomic mass of 16, but it has only 8 electrons. It is quite impossible for any atom to have more electrons than its mass no.

Overview of Cobalt

Atomic Number:27

Group: 9

Period: 4

Series: Transition Metals

Number of Electrons (with no charge): 27

Atomic Mass Average: 58.9332

but its atomic mass is not 16

How do you calculate the atomic mass of an atom?

The atomic mass can be calculated by adding the mass of protons, neutrons, and electrons. Electrons essentially have no mass, and protons and neutrons have an atomic mass of one. So looking at a common element of oxygen with 8 protons, 8 neutrons, and 8 electrons, we can find the atomic mass to be 16 (the number of protons plus the number of neutrons). An isotope of oxygen having 8 protons, 7 neutrons, and 8 electrons, would have an atomic mass of 15.


How many protons electrons and neutrons in the element oxgen?

Oxygen has the atomic number 8 and an atomic mass of 16.That means it has 8 protons, 8 electrons, and 8 neutrons.Rules for Calculating Protons, Electrons, and Neutrons in Uncharged CompoundsProtons = atomic numberElectrons = protons = atomic numberNeutrons = atomic mass - protonsRemember, if you have a charged ion, the number of electrons will be different.Oxygen is normally found as O2. A molecule of O2 will have 16 protons, 16 electrons, and 32 neutrons.


How many protons electrons and neutrons does s-2?

The atomic number of sulfur is 16 The number of protons is the same as the atomic number. The S-2 gains 2 electrons so it changes from 16 to 18. The atomic mass is 32. The atomic mass number minus the number of protons will give you 16 which is the number of neutrons. :)


An explination of what mass number and atomic number are?

The atomic number refers to the number of protons in the element. And since the number of protons = number of electrons, the atomic number is also the number of electrons in the element. The mass number of an element refers to the number of neutrons and protons in the element. &since electrons are negligible in mass, the number of neutrons can be found out by subtracting the atomic number from the mass number. Take for example, oxygen. Oxygen has an atomic number of 8 and a mass number of 16. Hence, from the atomic number it can be derived that it has: 8 electrons 8 protons While from the mass number, it can be derive that it has: 16-8 = 8 neutrons


How many neutrons are there in an atom with an atomic mass or 46?

The isotope sulfur-46 has 16 protons and electrons and 30 neutrons (the exact atomic mass is 46.000750).


How many atomic particles are in phosphorous?

The number of protons and electrons are equal to the atomic number. For P, this is 15. The number of neutrons is the atomic mass minus the atomic number (31 - 15 = 16). So Phosporous has 15 electrons and protons, and 16 neutrons.



How many protons neutrons and electrons are found in phosphorous?

Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16


How many protons and neutrons and electrons does the element sulphur have?

Sulphur has 16 protons, 16 neutrons and 16 electrons. The number of protons and electrons is the atomic/ proton number and the number of neutrons is found from the mass number (mass - number of protons = number of neutrons).


What is the number of electrons protons and neutrons of Sulfur?

Sulfur has 16 protons, 16 electrons and 16, 17, 18 or 20 neutrons ( the number of neutrons is different for each isotope).


Oxygen has eight protons eight neutrons and eight electrons what is the atomic mass?

The atomic mass number is always the sum of the numbers of protons and neutrons. In this instance, 16.


What element is a gas an has an atomic mass of 16 and 8 neutrons?

If the atomic mass (protons+neutrons) is 16 and 8 of the nucleons are neutrons, then 16-8 is the number of protons. In the periodic table one find that the element with atomic number no 8 is oxygen.


What element has an atomic mass of 16?

The element with an atomic mass of 16 is Oxygen(O).


A gas with 8 neutron and 8 protons?

That would be a gas with the Atomic 8 and mass number of 16 - Oxygen



If an element has 15 protons and 16 neutrons and 15 electrons than what is its atomic mass of the element?

The element is Phosphorous. Its mass=no. of protons+ no. of neutrons=15+16=31.


Atomic mass unit is determined by Oxygen-16?

The atomic mass unit is 1/12 from the atomic mass of the isotope 12C.


Molecular mass of sodium oxide?

Atomic mass of sodium is 23. The atomic mass of oxygen is 16. Therefore the molecular mass of sodium oxide is 23x2+16=62u.The atomic mass of oxygen is 16. Atomic mass of sodium is 23. Therefore the molecular mass of the given compound is 62 grams per mole.


Why is the approximated atomic mass of an atom with 16 neutrons 15 protons and 15 electrons 31 Daltons?

The atomic mass is determined by the contents of the [atomic] nucleus - the sum of the protons and neutrons; in this case the atomic mass {also called the atomic weight} is 31. A dalton is the mass of a hydrogen atom, or ion: that is, a proton.


Is the atomic mass of oxygen 16?

Oxygen is a non meta element. Atomic mass of it is 16.
