The meaning of ATOMIC NUMBER is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus and that determines t
When Dmitri Mendeleev drew up the periodic table, he grouped elements of similar properties. Based on the number of electrons, a scientist can determine which group to place an element into.This pattern is called a period(or row) on the periodic table. How do I read the periodic table? Th...
Anatomic numberis the number ofprotonscontained within the nucleus of an atom. Each element on the periodic table has a different atomic number. Currently, the atomic numbers of known elements range from 1 to 118. Thenucleus of an atomcontains protons andneutrons. An atom's electrons are found...
