Is mass number the combining capacity of an element?
No, mass number is the number of neutrons and protons that exist within the nucleus of the atom for a particular element. It is based on the idea that most of the mass of an atom derives from the nucleus.
How is the atomic number and mass number different?
The atomic number is the number of protons in the nucleus of an atom of any given element. The mass number is the number of protons and neutrons in the nucleus of an atom of an isotope of an element.
What is the mass number of a tungsten atom with 110 neutrons?
Tungsten is a non metal element. Mass number of it is 184.
A neutral atom has a mass number of 32 In what group does this element belong?
A neutral atom that is not an isotope with an atomic mass of 32 is sulfur. Sulfur belongs to group XVI.
If Atom A has mass number 239 and atomic number 93 and Atom B has a mass number 239 and atomic number 94 are atoms A and B of the same element and why?
No, the proton number decides, whether they are of the same element. In this case, they are isobars.
Why does not atomic mass of element represent the actual mass of the atoms?
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
What does the mass number of an atom represent?
The mass number is the sum of protons and neutrons in the atomic nucleus of a chemical element.
What does the mass of an element represent?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What does the atomic mass of the element represent?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

What does the atomic mass tell you about the atom?
The Atomic Mass of an element tells you the average mass of an atom in the element.
Atomic mass of an element?
The atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units.
What do the numbers on mendeleev's periodic table represent?
The Atomic number which is the number of protons in an atom's nucleus.
What does the atomic mass stand for?
the mass that the atom or the element has
Why atomic mass of atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
