The modern view of an electron orbital in an atom can best be described as Question 10 options:

A)

a three-dimensional space that shows the probability where an electron is most likely to be found.

B)

an elliptical path an electron follows around the nucleus.

C)

a spherical shell on the surface of which an electron can be found.

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.
