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 ...

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 ...

Microbial pathogens require nutrient metals in order to grow and cause disease. However, excess metals are toxic, so metal levels must be tightly regulated during infection. Vertebrates have evolved ...
