How do you find the neutrons for an atom?

Neutrons = Mass number - Number of Protons


How do you find the number of nucleons?

To find the number of nucleons in an atom, you add the number of protons and the number of neutrons together. Nucleons are the collective term for protons and neutrons found in the nucleus of an atom.


What Used to find the number of neutrons?

To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.


What is the number of an atom with 5 protons and 7 neutrons?

To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.


How do you find out how many neutrons a atom has?

Mass number = Atomic number (or number of protons) + Number of neutrons


How do you find the ratio of neutrons to protons?

The ratio of neutrons to protons in an atom can be calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons) of the atom. Mathematically, ratio of neutrons to protons = (Atomic mass - Atomic number).


Subtracting the Atomic number from the atomic mass?

To find the number of neutrons in an atom, you would subtract the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). The difference between the atomic mass and the atomic number gives you the number of neutrons in the atom.


How do you find the mass number given the proton electrons and atomic number but not the neutrons?

The mass number of an atom is the number of protons plus the number of neutrons. This is is the same as the number of electrons plus the number of neutrons since the number of protons is the same as the number of electrons in an atom.


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 an Osmium atom of mass number 188?

An Osimum atom with mass number 188 has 118 protons (atomic number for Osmium). To find the number of neutrons, we subtract the atomic number from the mass number: 188 - 118 = 70 neutrons.


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.


If an atom has an atomic namber of 20 and a mass namber of 53 how many protons and neutrons does that atom have?

uh, for one thing mass and atomic nUmbers. and the other: it has 20 protons and 33 neutrons. The atom would have 20 protons and 33 neutrons. The number of protons is always the same as the atomic number. To find the number of neutrons, you simply subtract the atomic number from the atomic mass. Atomic mass - Atomic number = number of neutrons (53 - 20 = 33) If you add the number of protons and the number of neutrons together, you should get the atomic mass.
