9 Neutrons I'm pretty sure it's 8. The number of protons should be equal to that of the electrons, so: 14A - 3P - 3E = 8N Unless, of course, it's the other way around, in which case: 14A - 3P - 8E = 3N I'm pretty sure it's the former, because any diagram of an atom I've seen has an equal number of protons and electrons, so if the Atomic Mass is 14 and there are 3 protons, there are 3 electrons, thus there are 8 neutrons. Answered by Nardo T. Icarus Actually, electrons have an atomic mass unit (AMU) of about .00054 (it would take 918 to make .5 AMU), so they do not account for any mass in an atom. Protons and neutrons have an AMU of 1 each, so an atomic mass of 14 minus atomic mass of 3 (protons) = 11 neutrons.

To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
Would you use atomic number or mass number or both to obtain the number of particles in an atom?
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
What is the atomic number of in atom?
atomic number is how much protons(positive atom) and neutrons(neutral atom) are there in an element. therefore an atom does not have an atomic number
What number is the atomic mass equal to?
Atomic mass is the number of protons and neutrons in an atom.
Atomic mass is determined by the number of protons plus the number of?
Atomic mass is determined by the number of protons and neutrons in an atom's nucleus.
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
What does the number of neutrons determine?
they determine the atomic mass of the atom
What do you have when you subtract the atomic no from atomic mass?
Atomic number is number of protons in an atom while atomic mass is the sum of protons and neutrons in an atom when you subtract you will get the number of neutrons in an atom.
If an atom has the atomic number of 4 and the atomic mass of 9.012 how many electrons will it have?
Atomic mass is protons + neutrons, and the atomic number (4) gives you the number of protons. Thus, this atom would have 5 neutrons.
Would you use atomic number or mass number or both to obtain the number of particles in an atom?
atomic number is the total number of protons OR electrons in an atom. mass number is the total sum of number of protons and neutrons. atomic number subtracted from mass number gives the number of neutrons in an atom. Mass number - atomic number = number of neutrons.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
How can you figure out the number of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?
uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.
What does the atomic number of an element tell you about its atom?
It would tell you how many neutrons make up the Nucleus of the atom.
What is the atomic number of in atom?
atomic number is how much protons(positive atom) and neutrons(neutral atom) are there in an element. therefore an atom does not have an atomic number
How many neutrons are in one atom?
The number of neutrons depends on the atom. In general, mass number = atomic number + number of neutrons.
