Question

Consider the electronic configuration of following elements and the statements given below. E = x, x3, x2 –3 F = x, 2x2, x + 1 A = x, x3, 2x + 1 B = x, x3 – 2 I. Chemical formula of the compound formed between F, A and B is F2AB4. II. Valency of E is 1. III. F is triatomic element. IV. B forms a divalent anion. V. F is a very reactive non-metal. The incorrect statements are

Answer 1

Answer:

ANSWER

X=2,8,2⟶ valance e

−

=2

Y=2,8,7⟶ Valance e

−

=1

So, the compound will be XY

Answer 2

The incorrect statements to the given questions are as follows:

• It is given to us that the following compounds have the given variants:
• E =  x, x₃ , x₂⁻³
• F= x, 2x₂, x⁺¹
• A= x, x₃, 2x⁺¹
• B = x, x₃⁻²

1. A chemical compound with the formula F₂AB₄ is not possible due to the given electronic configurations.
2. Valency of E cannot be 1.
3. F does not exhibit a triatomic state and thus is not a triatomic element

The incorrect statements for the given question are I, II, and, III.
