Question

In this way pb(NO3)2... Likhiye... Pb ka valency 4 hain... Please I am confused very much... Help me science lover​

Answer 1

$\Huge{\underline{\underline{\mathfrak{Answer \colon}}}}$

Formation of Lead Nitrate

Both lead and nitrate show variable valency

It is to be noted that in this case,

• Lead has a combining capacity + 2

• Nitrate has a combining capacity- 1

Don't let the signs confuse you,

They just signify whether the atoms donate or accept electrons.

• + implies they donate electrons and form cations which are positively charged

• - implies they accept electrons and forms anions which are negatively charged

Here,

Pb has a valency + 2 and NO3 has - 1 as its valency

On criss crossing,it forms

$\sf{{Pb}_{}{(N{O}_{3})}_{2}}$

This can be interpreted as follows :

If one atoms of lead combine with two atoms of the complex (Nitrate)
