What information would be requierd to determine the mass number of nitrogen?
You would need to know how many protons and neutrons are in the nucleus of a particular isotope of nitrogen. The number of protons, which is its atomic number, will always be the same, no matter which isotope is given, but the number of neutrons differs with different isotopes. For example, one isotope of nitrogen has 7 neutrons. To determine its mass number, find nitrogen on the periodic table, and you will see that its atomic number is 7. So this isotope of nitrogen has 7 protons. Now, add the 7 neutrons to the 7 protons, and you get a mass number of 14 for this isotope of nitrogen, which is called nitrogen-14. (Isotopes are named by their mass numbers.) Another isotope of nitrogen has 8 neutrons. Add the 8 neutrons to the 7 protons (atomic number), and you get a mass number of 15 for this isotope of nitrogen, called nitrogen-15.
Sn isotope of oxygen has an atomic number of 8 and an atomic weight of 18. how many neutrons does it have?
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons18 - 8 = 10
If the element Ag had a mass number of 108 how many neutrons would it have?
As silver atoms have 47 protons, the given isotope has 61 neutrons.
What describes an isotope of the commonly occuring oxygen atom which has 8 electrons 8 protons and 8 neutrons?
what is an isotope? An isotope is a different form of an element's atom that does not change the identity of the atom. I believe that the isotope would be Oxygen-16 due to the atomic mass of such an atom.
How many neutrons are in atoms of chlorine?
There should be 17, since the atomic number is how many protons (of which there are the same amount of neutrons). However, if it is an unstable isotope, it would have more neutrons.
How many neutrons in isotope?
It depends on what isotope you're talking about. To find the number of neutrons in a particular isotope, take the atomic mass and subtract the atomic number. For example, Na has a mass of roughly 23amu and 11 protons, so an Na-23 atom would have 12 neutrons.
What information would you need to calculate the atomic mass of an atom?
To find the number of neutrons in an isotope you subtract the atomic number from the mass number.
How many neutrons are in the isotope of aluminum 29?
If the isotope existed, it would have 16 neutrons.

How many neutrons have?
The number of neutrons in a nucleus depends on the element referred to and the specific isotope. For example how many neutrons in Carbon-12 would give an answer of 6
If the element Ag had a mass number of 108 how many neutrons would it have?
As silver atoms have 47 protons, the given isotope has 61 neutrons.
What determines the identity of an atom the number of protons the number of neutrons or the number of quarks?
mostly protons, the neutrons will affect it but it would still be the same element, just a different isotope.
How do you find the mass number if you have the atomic number of an isotope?
Mass number is the sum of protons and neutrons in the nucleus of the atoms of a particular isotope. The atomic number is the number of protons, so you would also need to know the number of neutrons. You could not determine the mass number from the atomic number alone.
How many neutrons and electrons does berylluim?
neutrons in berylium are 5 because Atomic mass - 9 Atomic number - 4 number of neutrons = Atomic mass - Atomic number = 9 - 4 = 5 neutrons = = berylium is metal = no berylium is not a true metal most of its properties are similar to the non metals.....
