No two elements may have the same atomic number. But two elements may have same Atomic Mass. Hence atomic number is better than atomic mass.

The atomic mass of iodine is less than the atomic mass?
The atomic mass of iodine is less than the atomic mass of all elements with greater atomic number.
What is larger the atomic mass or the atomic number?
The Atomic Number of an element is the number of Protons in its nucleus, that is what determines what element the atom is. The Atomic Mass is the total mass of Protons, Neutrons, and (negligable) Electrons, but that means the Atomic Mass will be larger than the Atomic Number.
Why atomic mass is always greater than atomic number?
Atomic number indicates the number of protons in the nucleus of a given element, whereas atomic mass results from protons and neutrons.
What has a different mass number than the normal atom?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Why actual atomic mass is greater than mass number?
Mass number = number of protons + number of neutrons in an atom
How is atomic number better than atomic mass?
Atomic Number tells you how many protons and electrons there are in a neutral atom.

Can the atomic mass be greater than the atomic number?
Yes

What is the atomic mass number of an isotope that has a atomic number of 6 but atomic mass of 5?
I think your understanding is confused. Atomic No. of '6' indicates the position in the periodic table, the number of protons, and the number of electrons. Atomic Mass is a number ( equal to or greater than atomic no.), which is the the total of protons and neutrons in the nucleus of an atom . So you atomic mass of '5' is incorrect as it is less than '6'. I think you mean 5 neutrons. If so the atomic mass is 6 + 5 = 11 This would be the isotopic element C-11 (Carbon eleven).

Why actual atomic mass is greater than mass number?
Mass number = number of protons + number of neutrons in an atom
What is the relationship between the atomic number and the atomic mass number?
Atomic number: number of protons in a nucleus unique to an element Atomic Mass number: number of protons + number of neutrons in a nucleus. May be a small range of values for a given element. Very roughly the atomic mass number is double the atomic number. For large elements it is more than double.

What is atomic mass and the number of calcium?
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
Mass number - atomic number equals?
Mass number minus the atomic number equals the number of neutrons. Mass number is the number of particles in an atom that have significant mass. Electrons are assigned a value of 0 since the mass is so much smaller than protons and neutrons. Protons and neutrons are similar in mass and are assigned mass number of 1. The formula for calculating atomic mass atomic mass = # protons + # neutrons.
