Explanation:
A periodic table can be defined as the table in which the row of chemical elements are present. All the elements of the row have same number of electron shells.
The arrangement of elements is based on atomic numbers, electron shell model and other chemical properties. The elements are placed in increasing order of atomic number.
This table does not give information about the occurrence of the elements.
There are 4 half lives of radium-226 in 6396 years. 15.0 divided by half 4 times (15.0/2= 7.5, 7.5/2 = 3.75, 3.75/2 = 1.875) equals 1.875 mg of radium-226.
