WebAs a reducing agent, a halide ion loses an outermost electron and the ability to lose this electron depends on the shielding effect and the ionic radius. The greater the reducing power of a halide, the more easily it can lose electrons. As you move down the group of halides, the attraction between the nucleus and the outer electrons decreases. WebInner transition elements are also known as f-block elements. The lanthanides and actinides are two groups of elements that make up the inner transition elements. They are belonging to periods 6 and 7. The 14 elements cerium through lutetium (atomic numbers 58–71) make up the lanthanide series. The actinide series includes the 14 elements ...

Properties. … WebThese elements react with halogens to form a variety of halides ranging in oxidation state from 1+ to 6+. On heating, oxygen reacts with all of the transition elements except palladium, platinum, silver, and gold. The oxides of these latter metals can be formed using other reactants, but they decompose upon heating.
WebTransition elements have the electronic configuration (n – 1)d 1 – 10 ns o – 2, Zn, Cd, Hg, the end members of first three series have general electronic configuration (n – 1)d10ns2. These elements do not show properties of transition elements to any extent and are called non-typical transition elements. Electronic Configuration of ...

WebThe halides of transition elements become more covalent with increasing oxidation state of the metal. Why? WebFor the heavier transition metals, higher oxidation states are generally more stable than is the case for the elements in the first transition series; this is true not only, as has been mentioned, for the properties of the oxo anions but for the higher halides as well.
