They are NOT normally arranged by atomic mass; instead they are arranged in the periodic table by their atomic number. The latter is the number of protons (or electrons) in a single atom of the element and it is a constant for the element. The atomic mass is an average of the isotopes of the element (in proportion to their abundance).While the atomic number is always an integer, increases in steps of 1 and elements that are a specific "distances" apart share similar chemical characteristic. On the other hand the atomic mass is rarely an integer, and occasionally it reverses the order laid out be the periodic table: for example, element 18, argon has an atomic mass of 39.948 which is greater than that of element 19, potassium with a mass of 39.098: this is because the predominant isotope of argon has 22 neutrons while that for potassium has 20 neutrons.
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.
The atomic mass of potassium is approximately 39.10 atomic mass units.
The gram atomic mass of nitrogen is 14.01 grams per mole.
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
Francium has a greater atomic mass than potassium. Francium has an atomic mass of around 223 u while potassium has an atomic mass of around 39 u.
the atomic mass of potassium is approximately 39
the relative atomic mass for the element potassium is 39.0983
No: 14.0067 is the gram atomic mass of nitrogen.
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
