Complex: A very general definition of complex is, 'A compound that results from the combination of a central atom or ion and a group of atoms/ions/molecules surrounding it'. As
The energy of second Bohr orbit of the hydrogen atom is -328 kJ mol-1, hence the energy of fourth Bohr orbit would be: (1) - 41 kJ mol -1 (2) -1312 kJ mol -1 (3) -164
Q. Define Oxidation state of an atom? Oxidation State: Oxidation state of an atom is defined as an apparent or formal charge on that particular atom in a molecule. In majorit
Lattice energy of an ionic compound depends upon: (1) Charge on the ion only (2) Size of the ion only (3) Packing of ions only (4) Charge on the ion and size of the io
Crystals and glasses Unlike a complex ion or molecule, which is a finite (often small) assembly of atoms, a solid has no fixed shape and size but can add atoms indefinit
