The ions plumbate are [Pb(OH)6]2- and the anhydrous forms (PbO3)2-, (PbO4)4-.
Symbol for sodium cation is 'Na(+)' Its valency is '1'.
The symbol for nitrate is NO3-. The valency of nitrate is -1.
The chemical symbol for gold is Au, and its valency is typically +1 or +3.
Ammonia is not an element and therefore does not have either a symbol or valency. Instead it has the chemical formula NH3.
Symbol is 'Hg' ( Hydragyrum ; from Latin ) It can exhibit two valerncies , viz, '1' & '2'. depending on its chemical environment.
Plumbate ion has a valency of -2. It is written as Pb4+ in ion exchange resins.
Symbol: Cl-Valency: -1.
Symbol for sodium cation is 'Na(+)' Its valency is '1'.
The symbol for nitrate is NO3-. The valency of nitrate is -1.
The chemical symbol for gold is Au, and its valency is typically +1 or +3.
Ammonia is not an element and therefore does not have either a symbol or valency. Instead it has the chemical formula NH3.
Symbol is 'Hg' ( Hydragyrum ; from Latin ) It can exhibit two valerncies , viz, '1' & '2'. depending on its chemical environment.
The symbol of Silver is Argentum or Ag and valency is positive 3
The symbol for fluoride is F. Fluoride has a valency of -1, meaning it typically gains one electron to achieve a stable electron configuration.
The chemical symbol of sodium zincate is Na2ZnO2. It is formed by balancing the valencies of sodium (Na), zinc (Zn), and oxygen (O). Sodium has a valency of +1, zinc has a valency of +2, and oxygen has a valency of -2. By combining these elements in the appropriate ratios, the compound is represented by Na2ZnO2.
Symbol of nitride is N and its valency is 3
Pb(OH)2-6 or PbO2-3 or PbO4-4 . More information is available, should you wish it, on the wikipedia plumbate page.
