Inthe accompanying table, which isa relatively simple type of periodic table, each position gives the name and chemical symbol for the element assigned to that position; its atomic number; itsatomic weight(the weighted average of the masses of its stable isotopes, based on a scale in which carb...
Mendeleev's periodic table of elements. The periodic table classifies all chemical elements according to their atomic number and chemical properties.

Atoms and the Periodic Table Atomic Structure ATOM: the smallest particle that has the properties of an element. From the early Greek concept of the atom to the modern atomic theory, scientists have built on and modified existing models of the atom. ...
example,carbon atomsalways have six protons;hydrogen atomsalways have one; andoxygen atomsalways have eight. Different versions of the same element, called isotopes, can have a different number of neutrons. Elements can also gain or lose electrons to become charged, in which case they are called...

with detailed knowledge when we say interactive, we mean that if you are studying the table then you should know about every term in it like atoms, valence shell, protons, electrons, and all the terms, then only you can say in front of everyone that you are interactive with the table. ...
The borders of the periodic table of the elements and of the chart of nuclides are not set in stone. The desire to explore the properties of atoms and their nuclei in a regime of very large numbers of electrons, protons and neutrons has motivated new experimental facilities to create new el...
