Symbol is 'Hg' ( Hydragyrum ; from Latin )
It can exhibit two valerncies , viz, '1' & '2'. depending on its chemical environment.
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.
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: 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.
Mercury
Mercury has 2 valence electrons.
Ammonia is not an element and therefore does not have either a symbol or valency. Instead it has the chemical formula NH3.
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
Hg is Mercury's symbol
