Chemists have recently explored protactinium's multiple resemblances to more completely understand the relationship between the transition metals and the complex chemistry of the early actinide ...

Heavier main-group elements have fundamentally different electronic properties from their lighter congeners. Until the last two decades of the twentieth century, these differences were often masked by ...

• In d-block, each horizontal row consists of ten elements as d-subshell can accommodate a maximum of 10 electrons. • The d-block elements having incompletely filled d-subshell are called transition ...

Ultrathin two-dimensional nanosheets of layered transition metal dichalcogenides (TMDs) are fundamentally and technologically intriguing. In contrast to the graphene sheet, they are chemically ...

Hafnium is a lustrous, silvery-gray transition metal. Discovered in 1923, it was the next-to-last element with stable nuclei to be added to the periodic table (the final one was rhenium in 1925).
