it tells you how much mass is in that object
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.
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.
The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.
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.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.

atomic mass is the no. of protons+no. of nuetron
The atomic number is the number of protons in the nucleus.The Atomic Number of an element helps us to locate that particuarler element on the Periodic Table of Elements.

The number of valence electrons tell us the group number of that element.

Calcium is a metal element. Atomic number of it is 20.
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
