Why do elements have a listed average atomic mass and not just atomic mass?

Because most naturally occurring elements are a mixture of isotopes, each having a different Atomic Mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.

Why does the atomic mass on the periodic table progressively changes left to right and top to bottom why?
Because there are increasingly more protons, electrons, and neutrons. Atomic mass is the average number of neutrons in all of the isotopes(different types) of a specific element, meaning you can sometimes have decimal masses. But, the atomic number is never a decimal because the atomic number is just a numbering system for all the elements.
What is the difference between the average atomic mass given on the periodic table and the mass of an atom?
An atomic mass is the mass without any changes to it. average atomic mass is is when you average it up that's all.Added:Atomic mass is the average of the masses of the naturally existing (i.e. mixture of) isotopes of one specific element.The atomic mass number is the sum of the protons and neutrons in the nucleus of an atom (specific for one specific isotope).
What is the atomic mass of AgBr?
To get the molecular mass we simply just add the atomic mass for the two elements. Silver = 107.8682 Bromine = 79.904 overall = 187.7722 g/mol
Atomic mass of an atom is called?
What do you mean? Atomic mass of an atom is the weighted average mass of all the naturally occurring isotopes of that element, measured in amu (=atomic mass unit). I do not know how do you want to call it, it is just atomic mass, average atomic mass, mass of an atom, atom's mass...
Atomic mass of copper?
Copper can be found on the Periodic Table of Elements. Copper's symbol is Cu, and the atomic number is 29. The atomic mass is hard to find searching the Internet, but here it is. The atomic mass for Copper is 63.546, also recognized as just 63.Atomic Number: 29Atomic mass: 63.546, or just 63**Note: The atomic mass for Copper and some other chemicals cannot be found on WebElements.
What is the atomic weight for copper?
Copper can be found on the Periodic Table of Elements. Copper's symbol is Cu, and the atomic number is 29. The atomic mass is hard to find searching the Internet, but here it is. The atomic mass for Copper is 63.546, also recognized as just 63.Atomic Number: 29Atomic mass: 63.546, or just 63**Note: The atomic mass for Copper and some other chemicals cannot be found on WebElements.
What do elements in the periodic table do?
The periodic table is just a way of grouping elements according to their atomic numbers. It helps scientists to understand why different elements react in different ways.
What is oxide atomic number?
Anything with "oxide" in the name is not an element, just a compound that contains oxygen. Only elements have atomic numbers, and that of oxygen is 8.

How do you find the atomic mass of the elements?
One should use an appropriate periodic table or look up in wikipedia by typing the elements name correctly and scroll down the collumn at the right (looking for 'standard atomic weight' or just 'atomic weight').This is not exactly the same as the mass number.

Why are atomic masses of elements usually not whole numbers?
The atomic mass listed in the periodic is found by taking the average of all the different isotopes of a given element found in nature, weighted for their natural abundance.Note that the atomic mass is not the same as the atomic weight. The atomic mass is the weight of one specific isotope of one atom, and is expressed in "atomic mass units" or amu. The atomic weight is expressed in grams per mole (g/mol) and is the weighted average of all the isotopes weighted by their abundance.See the Web Links for more information about atomic mass and atomic weight.

Why are f block elements are placed at the bottom of the periodic table?
Just for the size of the periodic table; with it in, it would almost double in length.
How can you use the word atomic radius in a sentence?
Please tell me your atomicnumber.You just did 'use atomic number in a sentence' by putting this question on-screen.You could even read the above question and answers aloud, and you will have done it again.I just couldn't believe my eyes when I realized that an atomic number is revealed by the number of protons in the nucleus of an atom!"What is your atomic number?" is NOT a good pick-up line, unless you are speaking to a scientifically-minded person.The atomic number of Helium is 2."The atomic number of Sulfur is 16."(Note that atomic number means the number of protons in the atom, that's why the term proton number is interchangeable with atomic number.)See the related Wikipedia link listed below for more information:
