That number is based upon the number of protons found in the nucleus. -See the related link liste dbelow for more information.
(It is not the number at which the atom may be reached...)
It means simply how many protons there are in an element. And and element is made up of the same types of atoms. If two elements or more are mixed, it is called a compound. Ex; Salt is a compound (mixture). It's made of Sodium (Na) and Chloride (Cl). Sodium and chloride are both separate elements. Salt is made of a certain type of atom and chloride is made with a different type.
The number of protons in an atomic nucleus.
The Atomic Number is the number of protons in an atom of that element's nucleus and is also the number of electrons in the electron shells of an electrically neutral atom of that element.
The elements on the periodic table are arranged in order of increasing atomic number.
by their atomic number in the periodic table by grouping the elements on the periodic table
atomic number
The elements arranged according to their atomic number in the table are called periodic table.
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons

Atomic Number
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
