The Atomic Mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus.
To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom).
A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)

Nitrogen has 7 protons and 7 neutrons The atomic mass of nitrogen is?
14 A proton has an atomic mass of approximately 1 AMU. A neutron also has an atomic mass of approximately 1 AMU. For most purposes, the atomic mass of an electron is considered to be negligible. Without knowing the number of protons this atom contains, one cannot calculate the atomic mass of the atom.
What does atomic mass do?
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
How is the number of neutrons in an atom found?
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
Why can you subtract the atomic number from the atomic mass and get the number of neutrons?
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
How can you find the number of neutrons in the isotope nitrogen-16?
Subtract the number of protons (atomic number) from the mass number 16. The atomic number of nitrogen is 7, therefore its atoms have 7 protons. The number of neutrons in the atoms of the isotope nitrogen-16 is 16 -7 = 9 neutrons.
What is the number of neurons in nitrogen?
Nitrogen is an atomic element and does not have any 'neurons' because neurons are nerve cells.I think you meant 'neutrons' :-Nitrogen has an atomic mass of 14.00674 and an atomic number of 7. As the majority of mass in an atom is in the nucleus and as the atomic number represents the number of protons in the nucleus, the number of neutrons ROUGHLY = the atomic mass minus the atomic number. In other words Nitrogen would have 7 neutrons in its nucleus.The fractional part of the atomic mass is because there are isotopes of nitrogen some with more or less neutrons than 7. In fact there are two stable isotopes of nitrogen: 14N and 15N the most common is 14N (99.634%).
How many neutrons can be found in an atom of nitrogen?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element For the most important natural stable isotope of nitrogen - 14N - the number of neutrons is 7.
What is the atomic number of nitrogen -14?
14 (mass number) - 7 (number of protons) = 7 (number of neutrons)
What is the number of protons and neutrons in N?
The atomic number of nitrogen is 7. So there are 7 protons and 7 electrons. The number of neutrons depends on the isotope. N-14 has 7 neutrons. N-15 has 8 neutrons. Number of neutrons = Mass number - Atomic number.
How do you calculate the mass of one Nitrogen atom?
Add the number of Protons and the number of Neutrons. The answer is 14 atomic mass
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.
How many protons and neutrons in N-15?
The number after the "N", 15, is the mass number. The mass number is the sum of the number of protons and the number of neutrons. So, if you find a periodic table, you can find the atomic number, which is the same as the number of protons. Because the atomic number of nitrogen is 7, it has 7 protons. Then we take the mass number (protons + neutrons) and subtract the number of protons to find the number of neutrons. 15 - 7 = 8 neutrons in 15N.
If an isoptope of nitrogen has 47 neutrons what is the atomic mass unit?
the answer is 7 nitrogen's atomic mass is 7
