Power's timely review in 2010 highlighted the inherent differences between the lighter and heavier main group elements, and that the heavier analogues resemble transition metals as shown by their reactivity towards small molecules. In this concept article, we present an overview of the last 10?
Those elements in which differetiating electron enters d-orbital are called d-block elements. They are also called transition metals because they are less electropositive than s-block but more electropositive than p-block elements.

Definition : d-block elements are defined as the elements in which the differentiating electron enters d-orbital of the penultimate shell i.e. (n-1) d-orbital where 'n' is the last shell. The general electronic configuration can be represented as, (n-1

10 Oxidative addition of the oligomers with two EH bonds to low valent metal complexes (Scheme 3(ii)) is much suitable for electron-rich late transition metals. The three-membered cyclic complexes with π-coordinated disilene (R2SiSiR2) ligands are isolated in the case of Pt or Pd.11 The ...
Step-by-Step SolutionStep 1: Definition of Transition Elements Transition elements are defined as chemical elements that have unpaired d-electrons in at least one of their stable cations. This means that when t
In conclusion, we have performed computational simulations on the possible incorporation of a range of elements into the Earth’s core, by considering the thermodynamic stabilities of corresponding Fe alloys. At high pressure, many elements, that are typically assumed lithophile or chalcophile, may co...
Water’s domain encompasses spirituality and the emotions. A balance of water brings about inspiration, wisdom and insightfulness. Too much water can create the feeling of unbalanced transition and the sense that you’re drowning emotionally. It can make you feel overwhelmed and overly social. When...
