Wo different atoms have four protons each and the same mass. However, one has a positive charge while the other is neutral. Describe what each atomic structure could be, listing the possible number and location of all subatomic particles

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.

c. orbital shape i hope this is correct
