Draw Bohr-Rutherford diagram for tritium

QUESTION 20 In Rutherford's model of atom, the size of the nucleus is estimated to be O 10:5 m O 10-10m O 10-15m O 10-20m

Whilst the vast majority of alpha particles passed through the gold foil with little or no deviation, a small fraction of them were scattered through larger angles, some even backwards.  Commenting on these findings Rutherford wrote “It was almost as incredible as if you fired a 15-inch shell at a piece of tissue paper and it came back and hit you.” Explain the implications of Rutherford’s results for models of atomic structure

Why is there zero probability of finding an electron at the center of the nucleus?

O 1s2s-2p-3s 3p O 1s°25 2p 3p? What is the atomic number Z of the element with the electron configuration 1s²25²2p°3s²3p®3d4s²? 04 09 O21 O 18 Finish Cancel
