According to modern periodic law,the properties of elements repeat at regular intervals when the elements are arranged in order of

The electronic configuration of an element $M$ is given below: $M: 1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10} 4s^2 4p^6 4d^{10} 4f^2 5s^2 5p^6 5d^{10} 5f^0 6s^2$. Choose the correct information regarding the element $M$ for its period number,block and group number respectively.

Atomic numbers of three elements $E_1$,$E_2$ and $E_3$ of the periodic table are $Z_1$,$50$ and $Z_2$ respectively. From the position of the elements shown in the figure,the value of $(Z_2 - Z_1)$ is:
