The ""size"" of an atom is sometimes defined by the radius of a sphere that contains 90% of the charge density of the electrons. Calculate the ""size"" of the hydrogen atom in its ground state according to this definition. (see below for useful integral; you do not need to fully solve for a numerical answer –you may leave in polynomial form. A guess and check approach will get you pretty close if you want to see the numerical answer.)

3/2a

Explanation:

The complete step by step answer is found in the attachment

you gotta add the following molecules so we can give u an answer

explanation:

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
