When you place north and south ends of the two magnets next to each other, what will happen?

He proposed that matter is composed of tiny, indivisible particles they called atomos which means “uncutable” in Greek.

THERE ARE SOME OBJECTS WHERE THE POSITIVE AND NEGATIVE CHARGES ARE EQUAL TO ONE ANOTHER.

He stated that matter is composed of vey small, spherical, indivisible particles called atoms.

Negatively charged subatomic particle orbiting the nucleus.

Who proposed that the atom is mostly empty space, with electrons orbiting the nucleus.

Positively charged center of the atom containing protons and neutrons.

Three-dimensional regions where electrons are most likely to be found in an atom.

Materials that allow electrons to flow freely from atom to atom.

They proposed that electrons have no predictable pattern and move in a region where electrons are likely to found called the electrons cloud.

What do you call to the experiment of Ernest Rutherford?

Region around the nucleus where electrons orbit.

How important are subatomic particles in your daily life?

It states that matter is composed of discrete units called atoms, as opposed to the obsolete notion that matter could be divided into any arbitrarily small quantity.

Materials that prevent the free flow of electrons from atom to atom.

He discovered the negatively charged components inside the atom through his experiments on cathode ray tubes.

He proposed that atoms chemically combine in simple, fixed, whole-number ratios to form compounds.
