Did you know?
WebJan 24, 2024 · An element is called a metal if it has one or two or three electrons in its valence shell (except hydrogen and helium, which are non-metals). Metal tends to lose its valence electrons in chemical reactions and complete its octet. Therefore, valency of metallic element \ ( = \) number of electrons in its valence shell. WebThe valence of an element is its ability to combine with other elements. The capacity of some elements to interact with other elements varies depending on the nature of the …
WebAnswer (1 of 7): This property is called as variable valency. Some elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more … WebJul 26, 2024 · Certain non-metals are also found to show more than one valence states e.g., P3+ and P5+. Variable valency may be due to different reasons and would be discussed over here accordingly. In transition elements (elements in which d orbitals are in the process of completion) the variable valency is due to the partially filled ‘ d’ orbitals ...
WebThus option A is correct. (B) Mercury shows +1 and +2 oxidation state. Thus it shows two series of salts. Thus option B is correct. (C) Mercury forms alloys with all metals except iron and platinum. Thus option C is correct. (D) Anhydrous Hg does not show variable valency. WebSome elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency. The reason behind Why they lose this extra electron is purely a matter of ...
WebMar 17, 2024 · Since, both zinc and mercury have completely filled d-orbital. So, they tend to lose only 2 electrons from their outermost shell. Hence, only show a valency of +2 and no variable valency. Thus, we can conclude that zinc and mercury do not show variable valency like d-block elements because their d-shells are complete.
WebThe valency of mercury is divided into two types: 1 and 2. Why do some Elements show Variable Valency? Consider this iron example: The metal (Fe)Iron has the number 26 in its atomic structure. Iron is an unstable molecule due to its 4 s 2 3 d 6 electrical structure. First, the two electrons in the 4s orbital will be eliminated. bowman topps baseball cardsNormally, the metals donate electrons from their valence shell, so as to form positively charged ions. However, some metals lose electrons from the shell next to the valence shell. In such a situation the element exhibits more than one electropositive valency. Such elements are said to have variable … See more The electrovalency of an element is equal to the number of electrons lost or gained by its atom during the formation of ionic bonds. The s-block elementsdo not show variable valency. … See more Certain elements have more than one valency. They exhibit variable valency.
