2+<\/sup>) have?<\/h2>\n\n\n\nThe elements that have 1, 2, or 3 electrons in the last shell donate the electrons in the last shell during bond formation. The elements that form bonds by donating electrons are called a cation.<\/p>\n\n\n\n
The zinc atom exhibits a Zn2+<\/sup> ion. The zinc atom donates two electrons in the 4s orbital to form a zinc ion(Zn2+<\/sup>).<\/p>\n\n\n\nZn \u2013 2e\u2013<\/sup> \u2192 Zn2+<\/sup><\/p>\n\n\n\nHere, the electron configuration of zinc ion is 1s2<\/sup> 2s2<\/sup> 2p6<\/sup> 3s2<\/sup> 3p6<\/sup> 3d10<\/sup>. This electron configuration shows that zinc ion(Zn2+<\/sup>) has three shells and the last shell has eighteen electrons. For this, zinc ions have a total of eighteen valence electrons.<\/p>\n\n\n\nHow to determine the valency of zinc?<\/h2>\n\n\n\n The ability of one atom of an element to join another atom during the formation of a molecule is called valency(valence). There are some rules for diagnosing valency.<\/p>\n\n\n\n
The number of electrons in an unpaired state in the last orbital after the electron configuration of an atom is called the valency of that element.<\/p>\n\n\n

Valency and valence electrons of zinc<\/figcaption><\/figure><\/div>\n\n\nThe oxidation state of zinc(Zn) is +2. The oxidation state of zinc +2 has been used in zinc oxide(ZnO). The valency of zinc in this compound is 2. The oxidation states of zinc depend on the bond formation.<\/p>\n","protected":false},"excerpt":{"rendered":"
The 30th element in the periodic table is zinc. The element of group-12 is zinc and its symbol is \u2018Zn\u2019. Zinc is a d-block element.
