The IP1,IP2,IP3,IP4 and IP5 of an element are 7.1,14.3,34.5,46.8,162.2 eV respectively.
IP1,IP2,IP3,IP4 and IP5 of an element are 7.1,14.3,34.5,46.8.162.2eV respectively. The element is likely to be Si. The jump in IP values exist in IP5 and thus, removal of fifth electron occurs from inner shell. Thus, the element contains four electrons in its valence shell.
The electronic configuration of silicon is {Ne}3s2,3p2. These 4 electrons need lesser IP than the fifth electron which has to be released from 2p6, requires very high IP.
Hence, option B is correct.
