The Chemical bond formed due to electron transfer is called ionic bond or electro valent bond Ionic bond will be formed more easily between the elements with low ioniation potential and high electron affiity. Energy changes involved during the formation of ionic compound can be calculated by Born- Haber cycle. Lattice enthalphy changes are directly proportional to the stability of ionic compound
In a multi – electron atom, which of the following orbitals described by the three quantum numbers will have the same energy in the absence of magnetic and electric fieldi) n = 1, l = 0, m = 0 ii) n = 2, l = 0, m = 0iii) n = 2, l = 1, m = 1 iv) n = 3, l = 2, m = 1v) n = 3, l = 2, m = 0
de-Broglie proposed the dual nature of electron and put forward his wave concept.The wave length of electron in an orbit was given by λ=hmv
