Answer to Problem 8LC
The atomic number is unique for every element.
Explanation of Solution
Henry Moseley put forth the modern periodic law in 1913. The physical and chemical characteristics of the elements are periodic functions of their atomic numbers, according to the modern periodic law. Thus, the elements are organized in the modern periodic table in increasing order of their atomic number.
Elements are identified by their atomic number. For every element, it will always be the same. The atomic mass of an element is the weighted average of its isotope masses. Thus, two different elements cannot have the same atomic number.
So, atomic number is a characteristic property of any element.
