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.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
Cobalt is an atomic mass of 58.93 atomic mass units
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Atomic number 6, atomic mass 12.
mass #-atomic#=# of neutrons
You would subtract the atomic number from the mass number.
mass #-atomic#=# of neutrons
You subtract the atomic number from the mass number.
Number of neutrons = Mass number - atomic number
mass no - atomic no = number of neutrons in an atom.
If you subtract the mass number by the atomic number you get the number of neutrons.
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
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Find out the mass number (A) of the specific isotope of the element. Find out the atomic number (Z) of the element (e.g. from the periodic table). Number of Neutrons, N = A-Z.
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
Find out how many protons (atomic number) and what the mass number of a particular element is. Then subtract the number of protons from the rounded mass number to get the number of neutrons in a particular atom.
