in lead nitrate why both sides brackets are used for the equation nitrate like pb(no3)2

Expert Answer
Nitrate is composed of group of atoms like one nitrogen atom and three oxygen atoms, 
If nirate group is attached to an metal atom who has valency ore than 1 one should draw it in a bracket to avoid confusion of numbers.
NaNO3 in this compound sodium has valency one hence no need to write a bracket,
while in case of Magnesium nitrate, Mg(NO3)2 one should write nitrate group in bracket, to avoid the confusion.
