WebErnest Zinck. 7 years ago. (1) There is an s orbital in every shell. There are 1s, 2s, 3s, 4s, 5s, etc. orbitals. (2) The s, p, d, and f orbitals are different from each other because they correspond to different types of vibration of the electron wave. (3) Each type of orbital belongs in its own energy subshell. WebSimple explanation: 5 th period in the periodic table has s-block , p-block& d-block elements…. hence max. no. of electrons accomodated by s, p & d sublevels = no. of elements in that period = 18 (2+ 6+10) Detailed explanation: For 5 th period, principal quantum number, n = 5 and values of azimuthal quantum number, l = 0, 1, 2, 3. imagination is the key to success
