Question

is there any way to calculate valency of compounds

Answer 1

You can determine the valency of a transitional element or a radical in a particular compound by noting how it combines with elements with known valency. This strategy is based on the octet rule, which tells us that elements and radicals combine so as to produce a stable outer shell of eight electrons. Simple illustrations of this strategy, note that sodium (Na), with a valency of +1, combines readily with chlorine (Cl), which has a valency of -1, to form sodium chloride (NaCl), or common salt. This is an example of an ionic compound in which an electron is donated by one atom and accepted by the other.

Answer 2

hey there....

yes there is way to calculate VALENCY of compound......

if no of electrons on valence shell are less than 4..,, then valency will be same as that of no of electrons....

if in case electrons are more than 4,, then formula is,, n - 4, where,,n = 5,6,7,8......
