WebScandium is very much a late starter compared to many of the other elements, due to its relatively low occurrence and the difficulty in obtaining it from its ores. For example, it … Web(i) Mn(II) ion shows maximum paramagnetic character amongst the bivalent ions of first transition series. (ii) Scandium (At. no. 21) salts are white. 2 ANS: (i) It is due to presence of five unpaired electrons. (ii) Sc3+ does not have unpaired electrons, therefore, cannot undergo d-d transition by absorbing light from visible region. WebAdult Education. Basic Education. High School Diploma.
