How is each element listed in the periodic table?
Three systems have been used to number families and groups:
- The older IUPAC system used Roman numerals together with letters to distinguish between the left (A) and right (B) side of the periodic table.
- The CAS system used letters to differentiate main group (A) and transition (B) elements.
- The modern IUPAC system uses Arabic numbers 1-18, simply numbering the columns of the periodic table from left to right.

What is the atomic number of an element?
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s 2 2p 2, since its atomic number is 6.

How are elements arranged in the periodic table?
In the periodic table, elements are arranged by their atomic number, with the smallest ranking first. A row in the table is called a period, and a column is called a family. The atomic radius decreases from left to right and increases from top to bottom. In the chemistry textbooks and dictionaries, there is a “the periodic table”.
What is the arrangement of the periodic table?
When the mystery of the atomic structure was discovered, the arrangement was based on the change from the relative atomic mass to the number of protons of the atom, the number of electrons outside the core or the number of nuclear charges, to form the current periodic table of elements.
What is secondary periodicity?
