Answer 1

the basic classification of modern period table is the characteristics features of atomic no.

Answer 2

Answer:

Explanation:

According to the differences in their chemical characteristics, elements are categorized.

• The periodic table is an arrangement of the chemical elements and are organized on the basis of their atomic numbers, electron configurations and recurring chemical properties.
• Elements are presented in order of increasing atomic number.

• Chemical properties of an element depend on the electronic configuration.
• The element behaves like a metal if it has 1, 2 or 3 electrons because it tends to lose electrons.
• In contrast, if it has 4, 5, 6 or 7 electrons, it is regarded as a non-metal because it needs electrons to become stable.

On basis of electronic configuration, elements are classified as:

1. s-block metals

2. p-block non-metals

3. d-block transition metals

4. f-block inner transition metals
