What else can I help you with?
If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus?
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.

What must you know about an atom to determine its mass number?
The number of protons and neutrons in its' nucleus.
What is the mass number for element A?
The mass number is the total number of protons and neutrons in the nucleus of an atom. To determine the mass number of element A, you need to know the number of protons and neutrons it has in its nucleus. The mass number is usually written as a superscript to the left of the chemical symbol (e.g. ^12C for carbon-12).
Which information would be required to determine the mass number of nitrogen?
To determine the mass number of nitrogen, you would need to know the number of protons and neutrons in its nucleus. Nitrogen has 7 protons, so the mass number can be calculated by adding the number of protons (7) to the number of neutrons in the nucleus.
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
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 is the mass number and what is the symbol?
Mass number is the number of protons and neutrons in the atomic nucleus of an isotope. In order to answer this question, you need to know the number of neutrons.
Why is proton number of an atom of an element different from the nucleon number of an atom of an element?
The difference between proton number (which is atomic number) and nucleon number, which is the number of protons and neutrons in an atom's nucleus, is the number of neutrons in the nucleus of a given nuclide. Nucleons are the components of an atomic nucleus. We know that both protons and neutrons make up an atom's nucleus. So the number of nucleons, which is the number of protons and neutrons, minus the number of protons, will equal the number of neutrons in the atomic nucleus.
An isotope is identified by its atomic mass number which is the total number of?
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
How may electrons neutrons protons are foundin the helium atom?
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
What is in the center of the atom?
Nucleus. Composed of Protons and neutrons. Can be sub-divided further but you probably don't have to know that. (quarks and muons and such.)
