Rutherford, 7 December 1912 and 3 January 1913, RCC.Hevesy , G. v. : The valency of the radio elements. Philosophic. Mag. (6) 25 , 390–414 (1913b).
Some metals, on the other hand, lose electrons from the shell next to the valence shell. The element has more than one electropositive valency in this case. Variable valency is a term used to describe such elements with variable valency. Valency of mercury or Valency of Hg is +1 an +2...
Electronic configuration of element is 2, 1, and the element is Lithium. The element will get nearest inert gas Helium configuration by loosing one electron. So its valency is 1.
All the elements in a group (family) have a common valency. For example , all the elements of the carbon family (carbon, silicon , germanium , tin and lead) have common valency four . However , some of these elements can also have valency two . Which of the following can have valency...

Some elements differ in their capacity to combine with other elements depending on the nature of the reaction; this property is called variable valency. For example, the iron in ferrous oxide exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. ...
We then describe how some elements can have multiple different valences and covalences. In other words, some elements do not always form the same number of bonds or have the same charge (if they form ions). We will explain the differences for several elements and some of the compounds ...
Valency: Any compound's chemical formula denotes the number of the element of which it consists and the proportion of each element in it. In writing the chemical formula of a compound, valency assists in determining the proportion of the substance. ...
Does valency influence the type of bonds formed? Yes, valency determines whether an element forms covalent or ionic bonds. 7 Does valency vary among different elements? Yes, each element has a unique valency depending on its electron configuration. 6 Do all molecules have the same atomicity? No...
