Typically to find the number of neutrons, you first round the Atomic Mass to the nearest whole number. After that to you subtract the number of protons (which is the same as the atomic number) from the newly rounded atomic mass and the resulting number is the number of neutrons. lets use Carbon for example:
Atomic mass: 12.01
Atomic mass rounded: 12.00
Number of Protons (same as atomic number): 6
(Rounded atomic mass - number of protons)=6
So Carbon has 6 neutrons.
Hope that is easy enough to understand.
The mass number of an atom is equal to the number of protons and neutrons that are in the nucleus of the atom. Atoms are the basic units of a chemical element.
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
The number of protons in a atom is equal to the atomic number, therefor Ag has 47 protons. The number of protons and neutrons in an atom is equal to the atomic mass, therefor (108-47= 61) Ag has 61 neutrons. The number of electrons is equal to the number of protons therefor Ag has 47 electrons.
Mass number!:)
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
The number of protons and neutrons is not equal. The equality is not a rule.
false
no, the mass number is number of protons in an atom, plus the number of neutrons.
Electrons are equal to the number of protons and the atomic number. To find the number of neutrons you must subtract the atomic number from the mass number.
No
Often, but not always, atoms with an equal number of protons and neutrons in the nucleus are stable and not radioactive.
No. The number of neutrons has no affect on the number of protons and electrons.
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
the total number of protons and neutrons in the nucleus.
mass number
It has 10 neutrons since the atomic number is equal to the number of protons and the isotope number is the number of neutrons and protons together.
It is equal to the difference between atomic number and Atomic Mass number. A+
