You can't. To find the mass number, you need to know how many neutrons are in the nucleus (mass number = # of protons + # of neutrons). The atomic number is equal to the number of protons, and the charge tells you the number of electrons indirectly (net charge of atom = # of protons – # of electrons). Neither of these things tells you anything about the number of neutrons, which is what you need.

How do you calculate the number of proton neutron and electron using atomic no and mass no?
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
How do you find atomic mass and mass number of isotope?
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.
What is the difference between mass number atomic mass and atomic number?
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.
How can you get the mass number and atomic number of element?
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.
Why do you subtract the atomic number from the mass number?
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.
How do you calculate the number of proton neutron and electron using atomic no and mass no?
atomic # = protons atomic mass - atomic number = neutrons atomic # - charge = electrons
How do you find atomic mass and mass number of isotope?
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.
How do you determine the number of protons electrons and neutrons present in an element by identifying its atomic and mass numbers from the periodic table?
Atomic number means number of protons present in an atom. Atomic number= number of protons. mass number = number of neutrons+ number of protons. So if you subtract the number of protons you get neutrons and if you subtract neutrons you get protons. mass number - protons= neutrons Mass number - neutrons = protons.
How do you figure out how many neutrons a atom has?
You find out the charge of nucleus (a number of protons), multiply it by mass of proton. Then substitute the result from the mass of nucleus and divide by mass of neutron. The result will give number of neutrons in the nuclei. waeva is da ansa hahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahahaha!!
How do you calculate the number of neutrons an element has in its nucleus?
You need to find the atomic number, and the atomic mass. The atomic number i the number of PROTONS in the nucleus, the atomic mass, or mass number, is the number of PROTONS and NEUTRONS in the nucleus. To find the number of neutrons you subtract the atomic number from the mass number.
An ion of iron has an 26 protons 30 neutrons and 23 electrons. What are its atomic number atomic mass and net charge?
Atomic number : 26Atomic mass : 55.845 Net charge : +3
When balancing a nuclear equation what two quantities are conserved when balancing a nuclear equation?
hi, the law of conservation of matter basically says that matter can't be destroyed or created. in nuclear equations, this is why the mass number and atomic number of the parent isotope always equal the mass number and atomic number of the products. hope this helps
