What is the atomic mass on the periodic table?
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.
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
What is the atomic mass of colbat?
Cobalt is an atomic mass of 58.93 atomic mass units
Is atomic mass unit a SI unit of an 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.
What will always be different in the isotops of atoms?
Atomic Mass
What is 4.00260 rounded to in atomic mass?
It is 4.0026 : the atomic mass can be a fraction.
Is the atomic mass of an element is always a whole number of atomic mass untis?
No.
What is the same in isotopes?
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
Is 40.08 the atomic number?
No. Atomic number is always a whole number. This would be the atomic mass.
Which of these is always equal to the molar mass of any element?
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.
Which is always equal to the molar mass of any element?
The atomic mass of an element is equal to its molar mass in grams/mol.
Does the number of protons in an atom of an element always equal its atomic weight?
atomic weight = mass of protons + mass of neutrons
How come the relative atomic mass can be a fraction?
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.
Which is a factor in determining the average atomic mass of an element?
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
Is an element's atomic mass always indicative of its level of radioactivity?
no
