The valency of an electron is nothing but the number of electrons gained or lost during an chemical reaction.
if the number of electrons is more than 4 than we have to caluculate by his way: -(8-number of valence electron)
then if the valency is 4 or less than 4 then the valency is same as the valence electrons
if the number of electrons is more than 4 than we have to caluculate by his way: -(8-number of valence electron)

where is the mistake
arey question is valency of compound yaar
yeah
and compound has no valency
but i didnot write word compound only anywher
but u have not mention it
i think he mos spelled it
u have to mention ki compound has no valency
ok baba i wrote my thing
ok

compound has no valency BUT it is the element that has valency
when we write any any element with its valency then it is called ion.
e.g. Na, K, has ----- one valency we write Na+1 & K+1
Ca, Ba. Mg have ---- two valency each Ca+2 , Ba+2 ,,Mg+2
Al,has ---- three valencies----------- Al+3
these when come in contact with nonmetals accepts one,or two, or three electrons
to form a compound e.g. Na Cl , K Br .so Cl & Br also have one valency each
now when there is more than one elements in a species then the charge on
them is called valency e.g. CO3-2 . SO4-2 have two valency each
NOW I THINK YOUR QUESTION IS THAT HOW TO FIND THE CHARGE
ON THESE IONS [ CATION & ANIONS ]
E
e g. NH4 now it has +1 charge as--------------
NH3 + H+ ---------------> NH4+1
Please mark it brainiest answer because i give a full description which taken around 15 minutes of my life..................Please...................If i deserve.
