Question

What is the need for the arrangement of elements in an organised
manner?​

Answer 1

An element can be identified as a metal, nonmetal, or metalloid based on its placement on the Periodic Table. The vertical columns in the Periodic Table are called groups. The Periodic table can help easily determine the valence electrons for many elements. Elements in the same groups have similar properties.

Answer 2

Answer:

Elements are needed to be arranged in an organised manner because it helps us to identify the element whether it is a metal, non-metal or metalloid based on which the element is placed on the periodic table.

The vertical columns are called groups and the horizontal rows are called periods in the Periodic table.
