Where `a, b,c, d, e,f,g, h` ar `3^(rd)` period elements. If difference between atomic number of elements `b` and `e` is `x` and difference between atomic number of elements `c` and `f` is `y`. What is the value of `x-y`.

Text Solution

Verified by Experts

The correct Answer is:
0
a is Na, b is Mg, C is Ai, d is Si, e is P, f is S, g is CI,h is Ar.
`x = 3, y = 3`
`x - y = 0`
