What is the valency of Pb in PbO?
Originally Answered: What is the exact valency of lead? Nothing exact about it. Pb forms +2 salts that are essentially ionic; PbO is amphoteric. It forms many +4 compounds such as PbO2 and PbCl4 and lead tetraacetate that are strong oxidizing agents.
What is the valency of P Why?
The number of electronic configuration are 2,8,5. When the atom gains 3 electrons the orbit is filled. or otherwise the atoms should lose 5 electrons. the valency is the combining capacity of the atom. therefore the valency of phosphorus is 3 and 5.
Does PB have variable valency?
The valency of an element is always a whole number. Some elements exhibit more than one valency, i.e., they have variable valency….Do Some Elements Have Variable Valencies?
