Rutherford proved it it from his alpha-particle scattering experiment.
particle whose dimensions is less then that of atom are said to be subatomic particle . they may be charged or uncharged .eg neutron is uncharged subatomic particle where as electron ,proton , positron are charged subatomic particle.
The concept that matter is made up of particles called atoms was proposed by the ancient Greek philosopher Democritus. He theorized that everything in the universe is composed of tiny, indivisible particles called atoms.
John Dalton is credited with proposing the atomic theory, which states that all matter is made up of small indivisible particles called atoms.
Yes, but they lose the 'identity' of the element when they are divided.Atoms were once thought to be indivisible units of an element - the smallest thing that retained the characteristics of an element. The word comes from the Greek for indivisible/uncuttable ~ a+ temnein.It is now known that atoms contain protons, neutrons and electrons and that even these are composed of smaller particles called quarks.
Democritus believed that matter is made of tiny indivisible particles called atoms. He believed that the atoms have always been, and always will be, in motion; that there are an infinite number of atoms, and kinds of atoms, which differ in shape, and size.

The mass of unstable atoms can vary widely depending on the specific isotope and the decay process involved. Unstable atoms typically have a higher mass compared to stable atoms due to the presence of excess energy or additional subatomic particles. When unstable atoms undergo radioactive decay, they can transform into more stable elements by emitting particles and energy.

The Greek philosopher who proposed that everything is made of atoms was Democritus. He believed that atoms were indivisible particles that make up all matter in the universe.

Atoms are composed of protons, electrons and neutrons (save hydrogen-1, which lacks any neutrons). Protons and neutrons are baryons, which are made up of three quarks. Having said that, the quark, which is a fundamental particle, is smaller than an atom by a great deal. Further, the quark is smaller than either a proton or neutron, as both are made of three quarks. The electron is a fundamental particle, and it is smaller still than a quark.When we look at the fundamental particles as they are described in the Standard Model, only the photon and gluon, which are force carriers, are smaller. It should be noted that the way we relate "smaller" in this case is by stating a mass-energy equivalence and describing the mass of the fundamental particles in terms of energy. Use the link below to see a chart of the sixteen particles that make up the three generations of matter.

The scientist who proposed that all matter is made up of atoms was John Dalton, known for his atomic theory in the early 19th century. Dalton's theory stated that all elements are made up of tiny indivisible particles called atoms.
since you said chemistry this should be the answer, the one i have in mind.. in an atom there are protons and neutrons in the middle or nucleus, fling around that are electrons. protons, neutrons, and electrons are subatomic particles (makes the atom stable when it's the same number of all three. google it!

Neutral atoms of the same element can differ in the number of neutrons, which results in different isotopes of the same element. Isotopes have the same number of protons and electrons, but different numbers of neutrons.
