Are all transition metals rare earth metals? How do rare earth metals accumulate? What country has the largest reserves of rare earth metals? I hear a lot in the news about how China is affecting the United States because it is protecting its rare earth metals. ...
Transition metals are required trace nutrients that foster inter-microbial competition when limited, inhibit bacterial growth through host sequestration, or induce toxicity in excess. This review highlights recent evidence that transition metals influence multiple stages of C. difficile colonization and that...

Why do transition elements form colored compounds? Explain why +2 is the most common oxidation state for the transition metals. What are the general properties of the d-transition metals? Give reasons why most of the compounds formed by transition elements are...
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
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.
On the periodic table of elements, transition metals are elements with partially filled d orbitals, or that have the ability to form partially filled d orbitals. An orbital is a location in an atom where we'll most likely find an electron (a negatively charged subatomic particle); they ...

Secondary-progressive multiple sclerosis (SP-MS, SPMS) is a form of MS that follows relapsing-remitting MS. Most people diagnosed with RR-MS will eventually transition to having SP-MS. After a period of relapses (also called attacks, or exacerbations) and remissions the disease will start to...
