What is 1 proton 2 neutrons?

<P>proton + neutrons give you a nucleon. the nuceon(or protons +neutron) give you the overall mass of the atom. the mass of electrons is not included, i dont even think that it has mass at all. Hope you're answered?</P>


How do you get the decimal in an atomic mass?

To get the decimal in an atomic mass, you divide the atomic mass number by 100. For example, if the atomic mass is 23, dividing by 100 would give you 0.23.


Atomic mass is 201 what is the atomic number?

The atomic number is the number of protons in an atom's nucleus. Given an atomic mass of 201, this information alone does not provide the atomic number as different elements can have the same atomic mass due to isotopes. More specific information about the element is needed to determine the atomic number.


How do you figure atomic weight?

Atomic mass - Atomic weight are the same , so look at your periodic table and below every element it will give you atomic mass.


What two pieces of information can be determined from the atomic mass?

The number of protons and neutrons in the atom can be determined from the atomic mass. The atomic mass represents the average mass of the isotopes of that element in atomic mass units.

What information does an atom mass give you?

The mass of an atom gives you an idea of how heavy it is in relation to other atoms. It is the total mass of the protons, neutrons, and electrons in the atom. The atomic mass is typically measured in atomic mass units (amu).


What number does the number of protons plus the number of neutrons give you?

The mass number (similar to the Atomic Mass and not to be confused with atomic number) When the number of protons and neutrons is added the result will be its atomic mass or mass number.

Atomic mass of krypton?

Kripton is a non metal element. Atomic mass of it is 83.80.


What does the atomic mass minus atomic number tell you about the element?

Atomic mass minus atomic number will give you the average number of neutrons in that element. Bear in mind that atomic mass is based on the actual weight of that element, which is the result of whatever isotopes appear in nature; it is rarely based on only a single isotope.
