   How is the periodic table organized?

   • The periodic table is organized into periods and groups. Periods are horizontal rows of the periodic table. They represent elements having the same number of electron shells or energy levels. However, each element has one more proton than its preceding element.

   How are periods arranged in the periodic table?

   • Periods are horizontal rows of the periodic table. They represent elements having the same number of electron shells or energy levels. However, each element has one more proton than its preceding element. Thus, the periods are arranged according to the increasing atomic number of the elements.

   What is the arrangement of elements in the periodic table?

   • The arrangement of elements in the modern periodic table can be explained in terms of atomic structure which provides evidence for the model of a nuclear atom with electrons in energy levels. All substances are made of atoms. An atom is the smallest part of an element that can exist.

   How are atomic periods arranged?

   • Thus, the periods are arranged according to the increasing atomic number of the elements. There are seven periods, with the period number ranging from 1 to 7. In the first period, there are two elements, each having only one electron shell. As we go down the period, the number of electron shells increases [1-7].
