The Atomic Mass number is the mass of the nucleus in atomic mass units.
What else can I help you with?
What the atomic mass tell the total number of?
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 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 is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
What does the atomic number and mass tell you about the atom?
The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the atomic mass of carbon-12.The atomic mass is a term applied only to specific isotopes; the unit is the same as above. Is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.The atomic number, on the other hand, tells us how many protons are in the nucleus of an atom.IUPAC publish periodically tables of atomic weights - the last edition is from 2009-2010.For the atomic masses of isotopes the last published edition is The AME 2003 atomic mass evaluation, edited by Audi, Wapstra and Thibault.
Which of these makes up an atom's mass number?
The mass number of an atom is determined by the total number of protons and neutrons in the nucleus of the atom. It does not take into account the number of electrons, which are negligible in terms of contributing to the mass of an atom.
What does the mass number of an atom tell you about the atom?
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
What is the mass number and atomic number of an atom?
Atomic number tells how many protons are inside an atom's nucleus and therefore also how many electrons the atom has. An atom's mass number is the number of protons AND neutrons in the atom's nucleus and this will vary for each isotope of an element.
What the atomic mass tell the total number of?
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 tells an atoms mass?
This tells us that an atom of krypton has 36 protons in its nucleus. All you really need to find is something called the mass number.
What does the atomic mass tell us?
it tells us that the number is equal to the number of protons plus the number of nuetrons in the nucleus of an atom
What does the atomic mass tell you?
It tells you the average amount of protons and neutrons within the nucleus of an atom. In other words, atomic mass - atomic number (protons)= the number of neutrons within the nucleus.
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 is the name number tells you the amount of protons and neutrons in an element?
Number of protons + Number of neutrons = Mass number(number of nucleons)
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What is the mass number and what does it indicates?
The mass number of an atom is the sum of the numbers of protons and neutrons in the nucleus of the atom. It also indicates the total positive charge on the nucleus.
What does the atomic number and mass tell you about the atom?
The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the atomic mass of carbon-12.The atomic mass is a term applied only to specific isotopes; the unit is the same as above.

How is the mass number of a atom indicated?
The mass number is the sum of protons and neutrons in the nucleus of an atom.
