• Matter occupies space and exists as solid, liquid, or gas.
• Pure substances is a type of matter having an invariant chemical composition and distinct properties, single element, constant, physical, and chemical properties
• The Periodic table is extremely important to know the atomic number of an element.
• The following hidden elements are: Sodium, Potassium, Iron, Copper, silver, tungsten, antimony, tin, mercury, gold, and lead.
• John Dalton is a British chemist and physicist in the atomic theory.
• Niels Bohr is a Danish physicist who developed the model of atom with electrons revolving around the nucleus at fixed energy levels.
• Ernest Rutherford is a New Zealand-born British scientist who conducted experiments on alpha particles which led him to conclude that most of the mass of an atom was concentrated in its center.
• J.J Thompson is known for his Plum Pudding model
• The Plum Pudding model contains tiny positive charges scattered throughout a cloud of negative electrons.
• Atom comes from the greek word atomos and the first to invent it is Democritus
• Planetary model is the model where electrons orbit the nucleus of an atom in specific energy levels or shells.
• Atomic Orbitals have three dimensional regions where electrons are likely to be found.
• Ag

• Na (Sodium) is originally the Latin word "natrium"
• K (Potassium) is orignally the Latin word for kalium
• Cu (Copper) is from the Latin word "cuprum" from the Greak word "kupros" meaning crypus
• W(Tungsten) is from the German word "wolfrahm" meaning "wolf cream"
• Sn(Tin) is from the Latin stannum, a lead and silver alloy
• Hg (Mercury) is from the Latin word hydrargye that means mercury
