What does the number of neutrons determine?
they determine the atomic mass of the atom
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
How do you determine the number of neutrons in an isotope if you know the atomic number?
Subtracting the atomic number from the mass number gives the number of neutrons. The atomic number is the number of protons in the nucleus. The mass number is the total number of protons and neutrons in the nucleus and this is the number that is quoted against isotopes, for example fluorine-19 contains 19 protons and neutrons. Fluorine has an atomic number of 9 so it has 10 neutrons.
What do we do to determine the number of neutrons in a atom?
atomic number
What two factors determine the atomic mass of an elements?
neutrons and protons
What does the atomic nucleus contains?
The atomic nucleus contains protons (at least one) and zero or more neutrons.
How do you determine the isotope?
The atomic weight determines the isotope, which is determine by the number of neutrons.
How do you determine neutrons in an atom of sodium-20?
the atomic mass
What are counted in an an atom to determine mass number?
Atomic Mass: protons AND neutrons atomic number: just protons
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.
What subatomic particles are added to determine the atomic mass?
Protons and neutrons.
