Zinc is not consider as a transition metal because its compounds or ions (Zn2+) contain a full filled d-orbital or sub shell and are unstable.Moreover it have only one ion which is the (Zn2+). | EduRev Chemistry Question is disucussed on EduRev Study Group by 441 Chemistry Students. (b) Unique structure of mercurous ion – Unlike Zn and Cd, Hg exhibits +1 as well as +2 oxidation state. Zinc does not show variable valency Because of: 2:28 10.6k LIKES. Solution : Zinc contains completely filled d-orbitals and exhibit stable electronic configuration, therefore it does not easily lose their electrons and hence, does not exhibit variable valency. Zinc is a transition element but it does not show variable valency because: A. it does not form coloured salts B. it has two electrons in the outermost orbit C. it has incomplete d-subshell D. it has completely filled d-subshell 4. Can you explain this answer? Which element does not show a valency of 2 2:50 10.1k LIKES. View Answer. Nov 21,2020 - Zn and Cd metals do not show variable valency because:a)They have only two elements in the outermost subshellsb)Their d-subshells are co mpletely filledc)Their d-subshells are partially filledd)They are relatively soft metalsCorrect answer is option 'B'. (i) They do not show variable valency except mercury (ii) Many of their compounds are white. Thus mercurous ion exists as Hg 2 2+ and not as Hg + Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). People who have low levels of zinc appear to benefit most from zinc supplements. Zinc is the second most abundant trace element in the human body. Colds. Fe is transition metal and belongs to d-block in periodic table, they have variable oxidation state, the most common oxidation state of Fe is + 2 and + 3 . 6.1k VIEWS. 9.4k SHARES. 2.1k SHARES. Which of the following can show variable valency ? Zinc does not show variable valency Because of: 2:28 10.6k LIKES. 9.7k SHARES. Explain. 2.6k SHARES. It does not show variable valence, which might lead to it being preferred quite simply because it does not introduce the risk of free radical reactions. Both transition as well as non-transition elements show variable valencies. This kind of deficiency isn't common in the United States. Indicate 'principal' and ' secondary' valancies of central metal ion in the following complexes: ... Zinc does not show variable valency like d-block elements because. 9.7k VIEWS. Zinc deficiency. 9.4k VIEWS. These elements have and extra subshell of electrons beneath their valence shells. By using 2n^2, we can figure out no. MEDIUM. The atomic number of an element variable valency. 2.6k VIEWS. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Zinc is the 30the element in the periodic table. (iii) Their melting and boiling points are very low. 2.1k VIEWS. Evidence suggests that if zinc lozenges or syrup is taken within 24 hours after cold symptoms start, the supplement can help shorten the length of colds.
