de-Broglie
Davisson and Garmer
Heisenberg
B.
de-Broglie
Wave-nature of electrons was first demonstrated by de-Broglie's who gave following equation for the wave-length of electrons:
4d, 5p, 5f and 6p orbitals are arranged in the order of decreasing energy. The correct option is:
6p > 5f > 5p > 4d
6p > 5f > 4d > 5p
5f > 6p > 4d > 5p
5f > 6p > 5p > 4d
