The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number.
Take for example, Uranium: the mass number on the Periodic Table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons.
238-92=146

What is the mass number and how do you calculate it?
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
How many number neutrons magnesium?
A stable magnesium atom has 12, 13 or 14 neutrons. The atom with 12 neutrons is the most common one.
How many neutrons are in an atom of sulfur with a mass number of 35?
Sulfur is a non metal element. Mass number of it is 32.
How many proyons and neutrons does a oxygen atom have?
An oxygen atom typically has 8 protons and 8 neutrons in its nucleus.
How many neutrons are there in an element having a mass number of 155 and an atomic number of 63?
The number of neutrons in the nucleus of an atom is always the difference between the mass number of the atom and the atomic number of the atom. Therefore, in this instance, there are (155 - 63) or 92 neutrons in the atom.
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 do you calculate how many neutrons are in a atom?
Atomic weight minus number of protons.
The mass number is used to calculate the number of what?
The number of protons and neutrons in the nucleus
How do you calculate the mass of the atom?
Protons and neutrons= mass
The mass number is used to calculate the number of?
protons and neutrons in an atom. It is the sum of protons and neutrons in the nucleus of an atom.
How many neutrons are in an atom I?
A typical atom of iodine contains 74 neutrons.
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
How many neutrons in a selenium atom?
45 neutrons
What is the mass number and how do you calculate it?
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
How many neutrons does a stable atom of Zn have?
A stable atom of Zinc (Zn) typically has 34 neutrons.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
How many neutrons are in the center of a atom of niobium?
52 neutrons.
