The lower left number on an element refers to the standard atomic weight, meaning the average mass of the atoms of an element. This is in comparison to the relative Atomic Mass, which compares the average mass of the element to 1/12 the mass of Carbon-12.
Umm the whole number is the number of electrons and the number with a decimal pt it the atomic weight but im not sure which is in the lower left side but the decimal pt should tell which is which
actually i just did the assignment in my physical science class and the answer is subscript.
The number found below the element symbol on the Periodic Table is the atomic number. The atomic number is the total number of protons located in the nucleolus of the atom.
It is called a subscript.
