What is the definition of bond length? Group of answer choices

the distance between the two atoms is larger than the sum of their atomic radii

the distance between the two atoms is smaller than the sum of their atomic radii

No correct response

the distance between the two atoms is equal to the sum of their atomic radii

the distance between two electrons

C: No correct response

Explanation:

Bond length is simply defined as the distance between two atoms that are participating in a bond.

Now, looking at the options, none of the options correctly defines it this way. The closest is option E which is "distance between two electrons" but it uses the word electrons instead of atoms. Thus none of the statements are correct

The second energy level can hold total of 8 electrons.

Carbon has atomic number equal to 6. There are 2 electrons in the first energy level and rest of the 4 electrons are in the second energy level.

So only 4 are present in second energy level while it can hold total 8.

4 is half of 8. So the percentage of energy level filled is half of 100%, the answer is 50%.

50%
