Question

n, p and as have silimilar properties. check whether the avarge of atomic masses of N (14)and as (74.9) is equal to the atomic mass of p(31), could we call it as a dobereiner triad? Why? Give reason?​

Answer 1

Answer:

We assume that N, P, As follow the Dobereiner's triads. It follows that M(P)=

2

(M(N)+M(As))

M(P)=

2

(14+74.9)

=44.45

Absolute error in mass of phosphorous =44.45−31=13.45

Answer 2
