Select the appropriate statements and arrange them in a logical order to explain the bonding in BeF2. i. Each of the singly occupied hybrid orbitals on Be overlaps with a singly occupied 2p orbital on an F atom. ii. The unhybridized 2p orbitals on Be interact with the 2p orbitals on the F atoms to form pi bonds. iii. The 2s and one of the 2p orbitals on Be combine to form two sp hybrid orbitals. iv. A 2s electron is promoted to a 2p orbital on Be. v. The 2s electrons in Be are promoted to 2p orbitals. vi. Each of the singly occupied 2p orbitals on Be overlaps with a singly occupied 2s orbital on a F atom. a.v, vi, ii b. v,vi c. iii, i, ii d. iv, iii, i e. iv, iii, i, ii

the old alchemists made significant contributions to science even though there starting premises were off a bit. their conclusions after failure would steer them into better directions for investigation. science is no more than close observation and the initial mistakes result in rethinking and retrying experiments.

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

thats a little if u want the answer just look it up on google thats what i do haha : )
