how do you find an element's group
The atomic number is responsible for determining the 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
hydrogen
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
relative age
relative positioning
Absolute Age
K23 is a relative reference. For example: =K23*10
how do you find an element's group
The atomic number is responsible for determining the element.
The atomic number.
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
By determining the element's orbital diagram, or its electron configuration.

...age of the sample.
the relative atomic mass for the element potassium is 39.0983
