Each element on the periodic table has two numbers: the atomic number and the relative atomic mass. The atomic number is the number of protons in the nucleus, and the relative atomic mass is the total number of protons and neutrons (so the difference between them is the number of neutrons). The relative atomic mass is always the higher of the two.
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Cobalt is an atomic mass of 58.93 atomic mass units
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
Atomic Mass
No.
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
No. Atomic number is always a whole number. This would be the atomic mass.
The atomic mass of an element from the periodic table in atomic mass units (amu) is always equal to the molar mass of that element in grams per mole.
The atomic mass of an element is equal to its molar mass in grams/mol.
atomic weight = mass of protons + mass of neutrons
The relative atomic mass is the mean mass of the isotopes of an element. Since, by definition, these have different numbers of neutrons, their masses are different. This results in fractional values.
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
No, the element with the largest atomic mass is not always present in the highest percentage by mass in a compound. The percentage by mass of an element in a compound is determined by its atomic mass and the total mass of the compound. The composition of a compound can vary based on the number of atoms of each element present.
