The molar mass or atomic mass of a substance is known as the quotient of the number of grams to the total number of moles and is measured in grams per mole or AMU (atomic mass unit). The general mathematical formula for the average...
What is the atomic mass number of the unknown nucleus? Atomic mass number: Atomic number is the number of protons inside the nucleus of element. On the other hand, atomic mass number, A of any element is equal to the sum of its prot...

Au $3,324 (+27.00%↑) Ir $4,250 (-4.40%↓) Rh $5,400 (+18.00%↑) USD per troy ounce4 As of the most recent mid-month, here are the approximate exchange rates4 for those metals. Though iridium is the scarcest, its utilities are virtually all industrial and the public doesn’t...
Atomic Mass of Krypton Atomic mass of Krypton is 83.798 u. Note that, each element may contain more isotopes, therefore this resulting atomic mass is calculated from naturally-occuring isotopes and their abundance. The unit of measure for mass is theatomic mass unit (amu). One atomic mass uni...
The atomic symbol for gold is Au, which comes from the Latin name aurum, meaning “glow of the dawn.” This mellow yellow metal was so prized that it became the material used to create the first currency system thousands of years ago. Few materials have enjoyed a sense of worth as ...
What is the shape of an f orbital?Atomic Orbitals:Atomic orbitals are regions wherein electrons lie. Their shape and size are defined by their quantum numbers; in particular, the orbital angular momentum quantum number (azumithal number) defines the approximate shape of the orbital....
What is the atomic mass of an element?Question:What is the atomic mass of an element?Elements:There are currently 118 identified electrons organized according to increasing atomic number from hydrogen (#1) to oganesson (#118). Each element has either a one-letter or two-letter abbreviation call...
Define atomic number, mass number, and atomic mass. Why is it wrong to state that "the atomic mass of an atom of chlorine is 35.453 amu?" Consider the element Au (Atomic Mass = 197). What is the atomic number? What is the atomic mass of the total protons and neutrons in an atom?
