What are 4 patterns in the periodic table?
Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.
What are the properties of modern periodic table?
Characteristics of Modern periodic table
- The elements are arranged based on their increasing atomic number.
- There are 7 periods and 18 groups in the table.
- The inert gases i.e. He, Ne, Ar, etc.
- All the groups are divided into sub groups A and B except 0 and VIII group in the modern periodic table.
