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.

The ion is a lead ion with a 4+ charge. Its atomic number is 84, and its mass number is 208 (since the mass number is one less than the atomic mass for this particular ion).
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.
An isotope with 35 neutrons and a charge of 2+ means it has 33 electrons (atomic number - charge). The atomic number can be calculated by subtracting the number of neutrons (mass number) from the relative atomic mass, so in this case, the atomic number is 30 (65 - 35).
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. Protons have a positive charge and neutrons have no charge, contributing to the overall mass of the atom. The number of electrons, which have a negligible mass, is not included in the atomic mass.
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
To determine the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the atom). Neutrons are particles found in the nucleus of an atom and carry no charge.
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!!
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.
Atomic number : 26Atomic mass : 55.845 Net charge : +3
