Protons gradually increase or decrease.
They follow a pattern for valence electrons.
Groups are arranged as columns in the periodic table; the contained elements have similar properties.
They follow a pattern for valence electrons.
The elements are arranged in horizontal rows and vertical columns, the rows are called periods and the columns are called groups or families. All the elements of the same group have similar chemical and physical properties. The periods all show a similar pattern, with metallic elements on the left transitioning to nonmetallic elements on the right of the periodic table.

All the elements of the same group have similar chemical and physical properties. The periods all show a similar pattern, with metallic elements on the left transitioning to nonmetallic elements on the right of the periodic table.
they are arranged in the increasing order of their atomic number from left to right. the horizontal rows are known are periods and the vertical columns are known as groups. elements in the same group have same number of valence electrons and hence have similar properties. further the elements can be classified based on the orbitals in which the valence electrons enter and can be classified as s-, p-, d- or f-block elements.
