Question

The electronic configuration of three elements X, Y and Z are as follows : X -2,4 Y - 2,7 Z - 2,1 Which two elements will combine to form an ionic compound with correct formula?

1 point

XZ3

YZ

Y2Z

X2Y​

Answer 1

Answer:

xz3 .... please thanks my answer a lot

Answer 2

Electronic configuration of,

• X = 2, 4

∴ Valency = 4 + (can lose 4 e- to become stable.)

• Y = 2, 8, 1

∴ Valency = 1 +

• Z = 2, 8, 7

∴ Valency = 1 - (can gain 1 e- to become stable).

So, compound formed by X & Y = not possible

[Compounds only form by reaction of anions and cations.]

By X & Z = X4+ x Z- = XZ4 (not given in options)

By Y & Z = Y+ x Z- = YZ (b).

Therefore, the correct option is B.
