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.
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.
How are mass number and atomic number of an element related?
The mass number is always greater than or equal to the atomic number. Beyond that it's not really possible to say.
Why does not atomic mass of element represent the actual mass of the atoms?
Because the gram atomic mass of an element is the mass in grams of Avogadro's Number of atoms. To find the actual mass of a single atom, the gram atomic mass must therefore be divided by 6.022 X 1023.
What is the difference between Mass number and Relative of atomic mass?
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 bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is bigger atomic mass or atomic number?

Can the atomic mass be greater than the atomic number?
Yes
The atomic mass of iodine is less than the atomic mass?

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 changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2

Does boron have a greater atomic mass then carbon?
Which has a greater atomic mass,flurine

What element has a gram atomic mass that is greater than the gram atomic mass of the element with an atomic number higher by one unit?
Both argon and cobalt have this characteristic.

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 number and mass of carbon?
Carbon is a non metal element. Atomic number of it is 12.
