What is the definition of an atomic number? An atomic number of an element is the number of protons in all the atoms of that element. Atomic numbers are always whole numbers greater than zero, such as 1,2,3... since an atom cannot have a fractional number of protons. ...

Effective atomic number or EAN is a number that represents the sum of the total number of electrons surrounding the nucleus of an atom in a metal complex. The effective atomic number is abbreviated as Zeff. It is composed of electrons of the metal atom and the bonding electrons from the sur...

Is atomic mass the same as atomic number? Which isotope defines the atomic mass unit? What is the atomic mass of aluminum? What information does the atomic mass of an element provide? What is the average atomic mass of oxygen? What is the atomic mass of ammonia?
A ship with a housekeeping load of 10 kW, a generation efficiency of 50%, and a 30-day mission will need 78.32 tons of ammonia heat sinks, with a volume of 122.567 m3. All of these are rather optimistic assumptions, and it should be kept in mind that the added mass and volume of ...
. During the last decade there has been extensive experimental and theoretical interest in atomic systems (6,7,15–18), particularly for clusters of rare gas atoms and those involving metallic-type constituents. In view of the fact that the magic number patterns observed in the case of rare ...
