A6 In the modern Periodic Table, elements are arranged in the order of increasing proton numbers. A student tried to re-arrange the elements in the order of increasing relative atomic masses and got nearly the same arrangement.However, the elements, argon and potassium would have their positions...

The periodic table is a chart that reflects the periodic recurrence of chemical and physical properties of the elements when the elements are arranged in order of increasing atomic number(the number of protons in the nucleus).It is a monumental scientific achievement, and its development illustrates...
Why the elements are arranged in a table? The chemical elements are arranged in order of increasing atomic number. ... This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group. How many eleme...

Elements are the fundamental materials of which all matter is composed. The elements are arranged in increasing order of their atomic weight (the number of protons in the nucleus of an atom). The periodic table lists all the known elements and groups together those with similar properties. ...
In the modern periodic table, the elements are arranged in the increasing order of their atomic number. This arrangement is based on the modern periodic law, which states that the properties of elements are a periodic function of their atomic numbers. In the modern periodic table, each column ...
In the periodic table the elements are arranged in columns and rows according to increasing atomic number (see the table entitled Periodic Table). There are 18 vertical columns, or groups, in the standard periodic table. At present, there are three versions of the periodic table, each with ...
