Because when you write the electron and orbital notations for elements, those are the elements that end in the p-orbitals.
This is called the "Periodic Law" or "Principle of Periodicity".
The answer to, ' when repeating chemical and physical properties of elements change periodically with the elements' atomic numbers it is called the?'Periodic law, is the answer. PERIODIC LAW !orPeriodicity of the chemical elements properties.
In the modern periodic table, the elements are arranged in order of increasing atomic number.
The horizontal rows of elements in the periodic table are called periods.
The elements located in the first column, group IA on the periodic table, are called alkali metals.
It is called the Periodic Table of Elements.
On the periodic table the elements are called groups.

Metals tend to form bonds by gaining electrons.
This is called the "Periodic Law" or "Principle of Periodicity".
The Periodic Table of the Elements, sometimes called just the Periodic Table, is the document in which elements are organized by their properties. It was created in 1869.
