The Arrangement of Elements in the Periodic Table
The elements are arranged in order of increasing proton number from left to right and from top to bottom.
The arrangement of elements is discussed from the aspects of groups, periods, proton number and electron arrangement.
The vertical columns in the Periodic Table of Elements are called Groups.
There are 18 groups of elements in the Periodic Table of Elements.
The number of valence electrons will determine the position of the group of an element
The horizontal rows in the Periodic Table of Elements are called Periods.
There are seven periods in the Periodic Table of Elements.
The number of shells filled with electrons will determine the position of an element in a period.
Position of the Group of An Element
With One or Two Valence Electron
With Three to Eight Valence Electrons
Group = Number of valence electrons
Group = Number of valence electrons + 10
