Ancient civilizations believed that all matter was made up of 4 basic “elements”, which were defined as:

• air, fire, earth, water

• carbon, hydrogen, oxygen, nitrogen

• hydrogen, oxygen, water, air

• earth, wind, fire, steel

Most historical records consider _________________________ as the Father of Modern Chemistry.

• Isaac Newton

• John Dalton

• Antoine Lavosier

• Albert Einstein

One of the early errors that many alchemists made was the idea that certain common materials and elements could be combined through fire and heat to produce ________. This idea was known as transmutation.

• silver

• energy

• water

• gold

Who was the Greek philosopher who first suggested that matter was composed of indivisible particles which he referred to as atomos?

• Dalton

• Democritus

• Einstein

• Plato

The first universally accepted theory on atoms was proposed in 1803 by what English school teacher?

• Winston Churchill

• John Dalton

• James Bond

• J J Thomson

Matter is conserved in a chemical reaction, where the mass of the atoms contained in the reactants before the reaction will be equal to the mass of the atoms formed in the products after the reaction is completed. This important discovery credited to Lavoisier is known as:

• The Law of Conservation of Matter

• The Law of Definite Composition

• The Third Law of Thermodynamics

• The Law of Ecological Balance

J.J. Thomson discovered the presence of the first subatomic particle, which was called the:

• atom

• proton

• electron

• nucleus

Through the Gold Foil Experiment, Rutherford showed the existence of what important atomic structure?

• the electron cloud

• the nucleus

• the alpha particle

• the neutron

One of the major differences between the 1st Atomic Theory presented in the 1800's and the Modern Model of the atom of today is:

• That atoms of all elements are the same.

• That atoms can be decomposed (broken down) into other atoms.

• That atoms do not contain a nucleus.

• The atom can be divided into subatomic particles.

History tells us that World War II forced the United States into a concerted scientific and military effort to develop an atomic bomb to stop Hitler’s aggression and the Japanese military threat. This research was part of the era known as the:

• The Atomic Age

• The Nuclear Age

• The Age of Enlightenment

• The Ice Age

• The Industrial Revolution
