The Atomic Mass of an element tells you what the mass of one mole (6.022 x 1023 atoms) of the element is. It sort of tells you the number of protons & neutrons in the atom, but that is not necessarily precise.
What else can I help you with?
What does atomic mass number tell us?
The atomic mass number tells us the total number of protons and neutrons in an atom's nucleus. It is used to determine the mass of an atom and is necessary for calculating the atomic weight of an element.
What is the atomic mass number of element d?
The atomic mass number of an element is the total number of protons and neutrons in its nucleus. It is denoted by the symbol A. If you provide the symbol or name of element d, I can tell you its atomic mass number.
What three things can the periodic table tell you about an element?
NameAbbreviationAtomic Number (number of protons = number of electrons)Number of neutrons in various isotopesAtomic massValenceGroup
How do you tell figure out the atomic mass?
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
What does an element's mass number tell us?
An element's mass number tells us the total number of protons and neutrons in its nucleus. It helps to determine the element's atomic mass and differentiate it from other isotopes of the same element.
What do the atomic number and atomic mass tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for atomic mass.
What do the atomic number and mass number tell you about an atom?
Atomic number tells the number of protons and electrons, but i don't remember for Atomic Mass.

Which particles account for the difference between the atomic number and the mass number?
The answer is that it is neutrons that account for the difference between atomic weight and atomic number. The atomic number is the number of protons or the number of electrons in the atom, since they are normally equal. The atomic weightis the sum of the total number of protons, electrons AND neutrons in the atom. Knowing both the atomic number and the atomic weight of an atom lets you know the number of neutrons in the atom (the isotope). Example: Uranium, Atomic Number 92, Atomic Weight 235. The atomic number tell you that the uranium atom has 92 protons and 92 electrons. The atomic weight tells you that it has a combined total of 235 protons, electrons and neutrons. Since you know from the atomic number that there is a total of 184 protons and electrons in the atom (92 + 92) and from the atomic weight that the total number of protons, electons and neutrons is 235 (92 + 92 + X = 235), you now know that there are 151 neutrons in that uranium atom. The atomic number and atomic weight together tell you that the uranium atom 235 has 92 protons, 92 electons and 151 neutrons.
What does the atomic mass describe?
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.
