Question

The diagram shows an outline of the periodic table.
Which of the elements U, V, W, X, and Y would react together in the ratio of 1:1?
A. U and X
B. U and Y
C. V and Y
D. W and X

Answer 1

Answer:

B. U and Y

Explanation

U is a first group alkali metal like(Na/K) specifically: Na

valency=1

V is a halogen(like Cl/F) specifically Cl

valency=1

and alkali metals and halogens react in ration 1:1 e.g NaCl

so UV will be compound

so B is the answer

other possible answer could be V and X as V is like Mg and X is like S

and MgS is their compound
