Introduction : The small central part of an atom is called the 'nucleus' of atom. Electrons move around the nucleus in the specified orbits in an atom. Nucleus has no direct influence on the chemical behaviour of the atom. Similarly chemical reactions do not bring any change in the compositi..

; paramagnetism due to unpaired electrons; increases with increase in unpaired electrons 6. Catalytic property Transition metals have active centers and large surface area; hence used as catalysts. Ex. Fe-synthesis of NH3; V2Os manufacture of H2S04; Ni- hydrogenation of oils 7. Complex formation Av..

Scoring well in Grade 12 Chemistry requires an understanding of both fundamental and complex topics like Atomic and Molecular Structure, Chemical Bonds, Conservation of matter and Stiochiometry, Gases and their Properties, Acids and Bases, Solutions, Chemical Thermodynamics, Reaction Rat..

In. a group ionization energy decreases from top to bottom because atomic radius increases. Though the nuclear charge in creases in a group, the size of an atom and the screening effect also increase with the increase in the number of shells. As a result, the outermost, ..

The electronic configuration of the outermost 2 2 2 1 orbit of chlorine atom is 3s 3p K 3p y 3p, . When a molecule is formed, the p ? orbitals of the chlorine atoms overlap along z direction (Fig 3.5). All the remaining atomic orbitals remain uninvolved in the bond forma..

It is the distance between the centre of the nucleus of an atom and its outermost shell. Or Atomic radius is defined as half the inter-nuclear distance between the combined atoms in a molecule. Unit : Angstrom : 1A = 10- |0 m Picometre : 1 pm = 10~ 1..

. Chain isomerism (Nuclear isomerism) Compounds with same molecular formula but differ in the arrangement of carbon atoms within the molecule are called chain isomers and the phenomenon as chain isomerism. For example i. Butane (C 4 H in ) has two isomers - normal butane and /sobutane. On..

) bonds are strong because the electron density is mainly concentrated along inter - nuclear axis (Fig. 10.2) In the formation of ethane molecule (C 2 H 6 ) each carbon atom undergoes sp 3 hybridization. Three of the four sp 3 orbitals of each carbon atom get overlapped by's' orbitals of ..
