The principal that states that an object at rest will stay at rest and that an object in motion will stay in motion is the law of .

Newton's first law

Explanation: The idea that objects only change their velocity due to a force is encapsulated in Newton's first law. Newton's first law: An object at rest remains at rest, or if in motion, remains in motion at a constant velocity unless acted on by a net external force.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the right answer is c i just did the question.
