  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

What is the description of John Dalton's atomic model?
Solid sphere model or bowling ball model.
He discovered the negatively charged components inside the atom through his experiments on cathode ray tubes.
J.J THOMSON
He stated that matter is composed of vey small, spherical, indivisible particles called atoms.
John Dalton
He proposed the planetary model.
NIELS BOHR
What do you call to the experiment of Ernest Rutherford?
alpha particle scattering experiment/ GOLD FOIL EXPERIMENT
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.
ATOMIC THEORY
They proposed that electrons have no predictable pattern and move in a region where electrons are likely to found called the electrons cloud.
Erwin Shrodinger & Werner Heisenberg.
Who proposed that the atom is mostly empty space, with electrons orbiting the nucleus.
Ernest Rutherford
He proposed that atoms chemically combine in simple, fixed, whole-number ratios to form compounds.
Dalton’s Model
He proposed that matter is composed of tiny, indivisible particles they called atomos which means “uncutable” in Greek.
DEMOCRITUS
How important are subatomic particles in your daily life?
Atoms are extremely important structures that make up all of the materials on earth. Atoms are in our bodies and they bond together to form molecules.
Positively charged center of the atom containing protons and neutrons.
ATOMIC NUCLEUS
Negatively charged subatomic particle orbiting the nucleus.
ELECTRON
Three-dimensional regions where electrons are most likely to be found in an atom.
ATOMIC ORBITALS
Region around the nucleus where electrons orbit.
ELECTRON CLOUD
Materials that prevent the free flow of electrons from atom to atom.
INSULATORS
Materials that allow electrons to flow freely from atom to atom.
Conductors
THERE ARE SOME OBJECTS WHERE THE POSITIVE AND NEGATIVE CHARGES ARE EQUAL TO ONE ANOTHER.
ELECTRICALLY NEUTRAL
2 TYPES OF ELECTRIC CHARGES
POSITIVE AND NEGATIVE
When you place north and south ends of the two magnets next to each other, what will happen?
They will attract each other.
