As you move down an element group (column), the size of atoms increases. This is because each atom further down the column has more protons and neutrons and also gains an additional electron energy shell.
Webatomic weight, also called relative atomic mass, ratio of the average mass of a chemical element’s atoms to some standard. Since 1961 the standard unit of atomic mass has been one-twelfth the mass of an atom of the isotope carbon-12. An isotope is one of two or more species of atoms of the same chemical element that have different atomic mass …
WebAs a result, relative atomic mass takes into account all of the naturally occurring stable isotopes of an element. The average mass is the relative atomic mass, which can be easily calculated from the percentage composition ( % abundance). An element’s relative atomic mass, Ar, is calculated as follows: The mass numbers of its isotopes orion\\u0027s arm posthumanWebTherefore, the order of the number of electrons in each shell of the argon(Ar) atom is 2, 8, 8.
