Negatively charged subatomic particle orbiting the nucleus.

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.

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

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

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

How important are subatomic particles in your daily life?

What do you call to the experiment of Ernest Rutherford?

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

What is the description of John Dalton's atomic model?

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