What are the subatomic particles of an atom? a. rotons, neutrons, and nucleus b. protons, neutrons, and electrons c. electrons, orbitals, and neutrons d. electrons, neutrons, and nucleus

B - Protons, Neutrons, and Electrons

Subatomic particles are the smallest particles within an atom.

A would be incorrect as the Nucleus is composed of said subatomic particles (Protons and Neutrons).

C is incorrect as Orbitals are used to describe the amount of electrons based on each shell, thus, deeming them inaccurate to the term of subatomic particles.

D is incorrect as, once again, the Nucleus is comprised of subatomic particles and is not a subatomic particle itself.

Hope this helps!

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.
