Subscript
Lead element appears below tin.It has symbol Pb and atomic number 82.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
Periodic table has 18 groups; see the link below.
The atomic number on the periodic table determines the number of electrons in the atoms of the elements. Each element has a unique atomic number, which corresponds to the number of protons in the nucleus and thus the number of electrons surrounding the nucleus in a neutral atom.
The elements on the periodic table are listed in order of atomic number, which corresponds to the number of protons in the nucleus of each atom. The atomic mass of each element is typically listed below the element symbol and represents the average mass of the isotopes of that element.
The number placed below an element symbol in a chemical formula is called a subscript because it indicates the number of atoms of that element in a molecule or compound. The subscript is written slightly below the element symbol to differentiate it from the coefficient, which applies to the whole molecule or compound.
a subscript Number of atoms of that element in the molecule.
The number placed below an element's symbol in a chemical formula is called a subscript. Subscripts indicate the number of atoms of that element in a molecule.
The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.

The average Atomic Mass
A subscript belongs immediately after the symbol of an element in a chemical formula to indicate the number of atoms of that element present in the compound. It is written as a small number at the bottom right of the element's symbol.
