Only when the nuclei of the element contain no neutrons. This occurs naturally only for hydrogen-1.

What does the atomical number represent?
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
Which is the average of the mass number of an element isotpes?
The atomic weight or atomic mass.
What is the difference between the atomic number and the atomic weight of the known elements as listed on the periodic table?
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
How can you get the mass number and atomic number of element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the atomic mass of an element the number?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Does the number of protons in an atom of an element always equal its atomic weight?
atomic weight = mass of protons + mass of neutrons
Is atomic weight and mass number the same?
Mass number: sum of protons and electrons in the nucleus of an isotope. Atomic weight: mass of a chemical element expressed in unified atomic mass units.
What is the difference of a atomic number and atomic weight?
Atomic number is the number of a chemical element in the periodic table of Mendeleev; it is equal in the neutral state with the number of protons or electrons. Atomic weight is the mass of a chemical element (considering the isotopic composition) expressed in atomic mass units.
What does the atomic mass of an element tell?
The gram atomic weight or gram Atomic Mass of a chemical element is the mass in grams of Avogadro's number of atoms of the element with the isotopic proportions found in nature.
What is a atomic number in a element?
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
Could Defferentiate the mass number and atomic element?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Is there an element that has the same atomic number and atomic mass?
No, there is no naturally occurring element with the same atomic number and atomic mass. The atomic mass of an element is the weighted average of the masses of its isotopes, which have different numbers of neutrons. The atomic number of an element is the number of protons in its nucleus, which determines its identity. Therefore, the atomic number and atomic mass are different for each element.
