Mendeleev was the first person to categorize the elements in a table and it was his studies and findings that paved the way for the modern-day periodic table. Classification of Elements and Periodicity in Properties- The elements with similar characteristics are grouped together and this is known as the classification of elements.

Physical Properties of Alkanes 1.

. General configuration of alkane is C_nH_2n2They exhibit tetrahedral geometry with a bond angle of 10947. With a standard atomic weight of circa 1008 hydrogen is the lightest element on the periodic table. The Modern or Long Form of Periodic Table.

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structureThe chemical symbol for Hydrogen is H. To learn detailed classifications Periodic properties of. The modern form of the periodic table follows the modern periodic law that the properties of the elements are the function of the atomic number.

Its monatomic form H is the most abundant chemical substance in the Universe constituting. Some salient physical and chemical properties of alkanes are. All the carbon atoms present in an alkane are sp3 hybridized that is every carbon atom forms four sigma bonds with carbon or hydrogen atoms.

There were many attempts at classifying elements including Dobereiners Triads and Newlands Octaves and Mendeleevs Periodic Table.
