take nitrogen as an example it has an atomic number of 7 that determines the number of protons as 7 positive charges so it takes 7 negative charges (electrons) to even it out so you have 7 electrons and protons. then you take the Atomic Mass which is 14.01 but you can round it to 14. then you take the atomic number and atomic mass and subtract them (14-7=7) so the number of neutrons is 7.

How do you determine the isotope?
The atomic weight determines the isotope, which is determine by the number of neutrons.
What two factors determine the atomic mass of an elements?
neutrons and protons
What determines the different isotopes from an atom?
The name of the element and the mass number (number of protons + neutrons) it is written e.g Uranium-235 or symbolically 235U
Which particles are in the nuleus of an atom?
Inside of an atom there are protons and neutrons. The protons determine the element whereas the neutron can determine if it is an isotope of that element. Of course there are many smaller particles inside of protons and neutrons like quarks and gluons and ... strings.
What particles are added together to determine atomic mass?
The number of protons, neutrons and electrons.
What does the number of neutrons determine?
they determine the atomic mass of the atom
How do you determine the amount of neutrons in the nucleus?
count it !
Do neutrons determine the conductivity of the atom?
no, but they determine if it is an isotope or not
How do you determine the isotope?
The atomic weight determines the isotope, which is determine by the number of neutrons.
What determine the mass and an atom?
Protons, neutrons and electrons
What do we do to determine the number of neutrons in a atom?
atomic number
Why must you know both how many protons and how many neutrons an element has in order to fully identify it?
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
What does the mass number determine?
The Number Of Protons & Neutrons In An Atom.
How do you determine neutrons in an atom of sodium-20?
the atomic mass
What two factors determine the atomic mass of an elements?
neutrons and protons
What subatomic particles are added to determine the atomic mass?
Protons and neutrons.
How do you determine neutrons in element?
subtract the atomic number from the mass number
