Question

How to find valency?​

Answer 1

Answer:

ork out which of the displacement (S), initial velocity (U), acceleration (A) and time (T) you have to solve for final velocity (V).

If you have U, A and T, use V = U + AT.

If you have S, U and T, use V = 2(S/T) - U.

If you have S, U and A, use V = SQRT(U2 + 2AS)

Answer 2

A :-) lets take a atomic number of 5 which is BORON so, the valency will be 8 - atomic number of boron.

Eg : boron ( Z = 5 )
Electronic configuration = k = 2 , L = 3
Valency = 8 - 5
= 3
