0 0 0. Elements in the same group of the periodic table have the same valency. 5 years ago. For example , the metal iron has valencies +2 and +3. No signup required!
It is 2 due to something called the inert pair effect. Login to reply the answers Post; How do you think about the answers? The valency of an element is related to how many electrons are in the outer shell.
"A valency grammar presents a model of a sentence containing a fundamental element (typically, the verb) and a number of dependent elements (variously referred to as arguments, expressions, complements, or valents) whose number and type is determined by the valency attributed to the verb.For example, the valency of vanish includes only the subject element (it has a valency of 1, …

Valency Of Lead. So the valency becomes 2 less than the group valency.☺ 0 1 0. Normally, 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. They're said to have variable valency.
The valency of an element is always a whole number. In the case of the metals exhibiting variable valency, we represent the lower valency by adding the suffix 'ous' to the name of the metal; to represent the higher valency the suffix 'ic' is attached to the name of the metal.

Some elements exhibit more than one valency, i.e., they have variable valency. The words valence and valency have two related meanings in chemistry.
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).
Valence describes how easily an atom or radical can combine with other chemical species. Examples : Iron, copper, tin, lead, sulphur, phosphorus. Thus metals like lead, tin, copper, mercury, iron etc exhibit variable valency. In such a situation the element exhibits more than one electropositive valency.
