All elements in a column of the Periodic Table have the same number of valence electrons. Since their reactivity (i.e. its bonding) depends on the number of valence eletrons, elements in the same column should have similar chemical and physical properties.
As you go from left to right, each element adds 1 more electron to it's available orbit and that when u get to the end of the row, all the shell gets full.
The elements on the Periodic Table are arranged in order of increasing atomic number.

It is called the Periodic Table of Elements.
In the periodic table chemical elements are orderd in periods and groups.
The periodic table.
CO3 is not placed in periodic table. Only elements are arranged in periodic table.
An element is a substance that cannot be broken into simpler substances by chemical methods, such as Neon or Oxygen.The periodic table contain all known chemical elements.
The atomic weight, or the number of protons.
the elements in the modern periodic table are arrange in the increasing order of their atomic numbers.
The elements arranged according to their atomic number in the table are called periodic table.
Element's atomic number decide its place in periodic table. They r arranged in increasing order.
The amount of electrons in each element.
A Periodic table The Periodic Table of the Elements.
Atomic Number
The periodic table contain all chemical elements, placed in a rational order.
Elements are arranged on the Periodic Table in the order of the atomic number, in groups and periods.
atomic number
The short answer is yes - the periodic table is about order.
They have simliar properties and same elements although later on more elements were added to the modern periodic table.=Both periodic tables have elements grouped by similar properties. Mendeleev's periodic table had elements arranged in order of increasing atomic mass in columns with similar properties. While many of the elements are in order of atomic mass on the modern periodic table, some are not, as the modern table has elements arranged in order of increasing atomic number.=
