Matter is discontinuous, and it is made of tiny particles called atoms
Explanation:
Matter is not a continuous structure, but it consists of tiny particles called atoms.
An atom consists of three types of particles:
Proton: the proton is in the nucleus of the atom. it has a positive electric charge of (also called fundamental charge). Its mass is .
Neutron: the neutron is also in the nucleus of the atom, but it has no electric charge. Its mass is similar to the mass of the proton (slightly heavier). Neutrons and protons are held together in the nucleus through the strong nuclear force.
Electron: electrons are found in a "cloud" outside the nucleus. Electron has negative electric charge equal to . Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
"if it is tested in a controlled setting with repeated results" is the statement among the choices given in the question that best describes that can possibly make this scientific claim valid. The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has helped you.<span> </span>
When a gas bubbles through water, small droplets of water are usually picked up along for the ride and are mixed in with the gas above the water inside the eudiometer tube. The water vapor takes up room, but isn't the important gas that you need to measure. The table of water vapor is needed to subtract the unwanted water vapor from the collection of gases.

. Its mass is much approximately 1800 times smaller than that of the proton, so it is considered as negligible.
