Class 10 Science Chapter 5 Periodic Classification of Elements – Important Topics

Periodic classification of elements have been done inorder to classify the elements according to their properties. Some of the periodic classification theories and tables include:

Newland’s law of octaves
Dobereiner Triad
Mendeleev’s periodic table

Newland’s law of Octaves: According to Newland’s law, when the elements are managed according to aggregate atomic masses, the physical and chemical properties of every 8th element are the same as that of the first.

Dobereiner Triad: Dobereiner identified a group of 3 elements with similar chemical and physical properties in the order of aggregate atomic masses and called it a triad.

Mendeleev’s Law: Madeleev’ law stated that the chemical properties and physical properties of elements are periodic purposes of their atomic masses.

The Modern Periodic Law states that- “ Properties of elements are a periodic function of their atomic number.” In the Modern Periodic Table, the elements are characterised in the form of Periods and Groups.

Some of the trends in periodic table include:

Metallic character
Non metallic character
Metalloids
Variation of atomic size
Electronegativity
