The elemnt with atomic number 3 is Lithium. There is no easy way of determining how many neutrons are in an atom, in Lithium there are two stable isotopes, 6Li with 3 neutrons and 7Li with 4. The most common is 7Li.
If you ever have to guess because you dont have access to Wikipedia or a table of the elements which shows the different isotopes, there are often the same number of neutrons as protons in stable isotopes.

How do you tell how many neutrons are in an atom with the atomic number of 12?
To find the number of neutrons in an atom with an atomic number of 12 (which is the number of protons), you would subtract the atomic number from the atomic mass number. The atomic mass number is the sum of the protons and neutrons in the atom. For an atom with an atomic number of 12, the number of neutrons can be calculated by subtracting 12 from the atomic mass number given for that specific atom.
How many neutrons are in one atom?
The number of neutrons in one atom can vary depending on the element. Neutrons are one of the three main subatomic particles found in an atom, along with protons and electrons. The number of neutrons in an atom is calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom.
How do you figures out how many neutrons are in an an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
How do you calculate how many neutrons there are in a atom?
The atomic weight minus the number of protons = the atom's neutrons.
How many neutrons are in one atom in fluorine?
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.
How do you figure out how many neutrons are found in an atom?
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
How do you find out how many neutrons a atom has?
Mass number = Atomic number (or number of protons) + Number of neutrons
How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic?
To find the number of neutrons in an atom, you subtract the atomic number (which represents the number of protons) from the atomic mass. If the atomic mass is 36 and the atomic number is, for example, 18 (like Argon), you would calculate it as 36 - 18 = 18 neutrons. Thus, the atom would have 18 neutrons in its nucleus.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
If the atomic mass of the atom is 48 and it contains 20 protons, then the atom contains 28 neutrons. This can be calculated by subtracting the number of protons from the atomic mass, since the atomic mass includes both protons and neutrons.
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.
How many neutrons does an atom of 21Ne have?
An atom of 21Ne has 11 neutrons. This is determined by subtracting the atomic number (which is 10 for neon) from the atomic mass number (which is 21 in this case).
How many neutrons are in a atom of magnesium?
A magnesium atom typically has 12 neutrons. Magnesium has an atomic number of 12, indicating it has 12 protons which is equal to its number of electrons in a neutral atom. The number of neutrons can be calculated by subtracting the atomic number from the atomic mass of magnesium, which is approximately 24.305 amu.
