If you had looked in the Periodic Table, you would have seen that the element Oxygen has an Atomic Mass of 16 (or more precisely 15.9994) and if you were to take that atomic mass and subtract the atomic number from it (i.e. 8) you would get a difference of 8 which is the number of neutrons it contains. In short, oxygen is that element.

What is the atomic mass of the element silicon?
Silicone is a non meta element. Atomic mass of it is 28.
Oxygen has eight protons eight neutrons and eight electrons what is the atomic mass?
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. Therefore, atomic mass of oxygen is 15.
If atomic mass of 16 and atomic number of 8 this means the number of neutrons in this type of oxygen is?
The atomic number refers to the number of protons in an element. The mass number can be used to indicate the number of neutrons because both protons and neutrons have a mass of about 1. An oxygen atom has 8 protons and 8 neutrons.
If an atom of an element has a mass number of 31 and 16 neutrons in its nucleus what is the atomic number of the element?
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
What is the name mass number and atomic number of an element with 16 protons and 16 neutrons?
Well, if an atom has 16 protons, then it is Sulfur, which is a non metal. If it had 16 neutrons, then it would be another isotope of sulfur, which would make it Sulfur-32. Then, unless it has a charge, there would also be 16 electrons.
What is the atomic mass of the element silicon?
Silicone is a non meta element. Atomic mass of it is 28.
How many neutrons does suflur have?
Sulfur has 16 neutrons. To find out how many neutrons an element has you subtract the atomic number of that element by the atomic mass. omg thank you so much

The atomic number refers to the number of protons in an element. The mass number can be used to indicate the number of neutrons because both protons and neutrons have a mass of about 1. An oxygen atom has 8 protons and 8 neutrons.
How many neutrons does an element have if the proton number is 15 and its atomic mass is 31?
31 - 15 = 16 neutrons
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.
The atomic weight of an element whose atoms contain 8 protons 8 electrons and 8 neutrons is?
That would be an oxygen isotope and it's Atomic Mass would be 16. (Protons + Neutrons) The mass of an electron is so minuscule that it is not even factored into the mass.
What is the Atomic mass is the number of?
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.
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 do you figure out how many protons and neutrons are in an atom?
you use the mass number for the neutrons. you take away the atomic nomber from the mass number and the answer is the number of neutrons. for the electrons and the protons you just write the atomic number.
If an atom of an element has a mass number of 31 and 16 neutrons in its nucleus what is the atomic number of the element?
12. the atomic number of an element is the number of protons in it's nucleus. The mass number is the number of protons+neutrons. Therefore the element has (32-20)12 protons.
How many neutron are in oxygen?
There are 8 neutrons in oxygen. You can determine the number of neutrons in any element by subtracting the atomic number (which is 8 for oxygen) from the atomic mass, rounded to the nearest whole number (which is 16 for oxygen). This is because the mass of any element comes mainly from the protons and the neutrons - the mass of the electrons is too tiny to be a significant contribution. The atomic number corresponds to the number of protons in an element, so when you subtract it from the element's total mass, you are left with the number of neutrons.
