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...
Elementsin the periodic table are arrangedin order of increasing atomicnumber and placed in vertical columns (groups)andhorizontalrows(periods). .The elements across the periods show repeating patterns inchemical and physical properties. This is called periodicity. ...
The most commonly used form of the modern periodic table, sometimes called the long form, in which the elements are arranged in seven horizontal rows in order of increasing atomic number. Each element is identified by its symbol placed...
