After the IUPAC rules, Atomic Mass is an expression used only for the mass of isotopes (in Atomic Mass units).
the atomic mass is how heavy one mole of the substance would be, it takes into account only the mass of the protons and the neutrons, as the mass of the electrons is insignificant
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
I assume you mean relative atomic mass, which is the average atomic mass of an atom of the element. Atoms of a particular element will usually have several isotopes. An isotope is an atom where the number of neutrons is specified as well as protons, e.g. "carbon-13" is a radioactive isotope of carbon with an atomic mass of 13 because it has 6 protons and 7 neutrons.
The relative atomic mass of an element is calculated by adding together the sum of each atomic mass multiplied by its proportion.
Relative atomic mass = (m1 * p1) + (m2 *p2) + (m3 * p3) + ... where m = atomic mass of isotope and p = proportion of isotope.
e.g. element X is has following isotopes:
20% have a mass of 30
0.3 have a mass of 31
1/2 have a mass of 32
Relative atomic mass = (30 * 0.2) + (31 * 0.3) + (32 * 0.5)
= 31.3
So the average atom will have a mass of 31.3 atomic units.
The Atomic Mass is the weighted average mass of the isotopes of an element
it tells the weight of ine atom in the element
atomic mass is the number of protons in the nucleus of an atom.It can also be equal to the number of electrons in a neutral atom
mass in a atom
I assume you mean the atomic mass. Its atomic mass is 204.3833g/mol
Beryllium Atomic number: 4 Atomic Mass: 9.012
AMU= atomic mass unit
I assume you mean the atomic mass. Its atomic mass is 98.91g/mol
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.

Bromine has the atomic number 35, which means there are 35 protons in the nucleus of an atom of bromine.The mass number (also known as the atomic mass number) of an element is the sum of the protons and neutrons in the nucleus.Bromine's mass number is 80, so there must be 35 protons and 45 neutrons in an atom of bromine.Sorry we do not know what you mean by "newtrons" or "deos".
AMU= atomic mass unit
You mean molecular mass or moler mass, not atomic mass! Add up the atomic masses of all the atoms in the molecule.
I assume you mean the atomic mass. Its atomic mass is 98.91g/mol
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
The atomic radius is the same thing as the atomic mass.
if you mean phosphorus then the atomic mass is 30.973762. i don't think phosphate is an element.
Atoms (not planets) have "atomic weight", usually called "atomic mass" now. Perhaps you mean : What is Jupiter's mass? Jupiter's mass is about 318 times the mass of our Earth.
AMU stands for atomic mass unit. 1 amu is 1.66053892 times 10 up to the negative 27 kilograms.
