The modern periodic table is modified form of the mossleys periodic table,which was yet modifiied form of the mendileevs periodic table,which was based on the principle-atomic mass is the periodic function of the elements.Mossley changed the periodicity of elements to be the periodic functions of their atomic numbers.hence in the modern periodic table we can find,the repeatation of certain properties of elements after definite intervals and hence the periodic table has groups and periods the elements inside which,are similar.this is possible because across a period electrons increase by 1,keeping shells sama,and down a group,outer electrons remain same,but shells increase by1.
Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.
Metallic properties generally increase as you move down a group in the periodic table and decrease across a period from left to right. This is due to the increasing atomic size and decreasing electronegativity down a group, which enhance metallic character. Conversely, as you move across a period, the increasing nuclear charge holds electrons more tightly, reducing metallic behavior. Thus, metallic properties are more pronounced in heavier elements and those located towards the left side of the periodic table.
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
The density properties generally change as you go down the columns of the Periodic Table by increasing.
Yes, shielding increases as you move down a group in the periodic table.
The number of shells in periodic table increase down the group, i.e., vertically.

Periods (across the Periodic Table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
The melting temperature properties generally change as you go down the columns of the Periodic Table by decreasing for metals and increasing for non-metals.

The melting temperature properties generally change as you go from left to right in the periodic table by going down/decreasing.
Electronegativity increases as we move from left to right on the periodic table.

Periodicity on the periodic table refers to the repeating pattern of physical and chemical properties of elements as you move across or down the table. This periodic pattern is a result of the elements having similar outer electron configurations within the same group or period. Periodicity helps to predict an element's properties based on its position in the periodic table.
