• Chemistry is the study of matter, analyzing its structure, properties and behavior to see what happens when they change in chemical reactions. (Fact)
• Matter is the basic unit of a chemical element. (Bluff, atom)
• Proton has a negative charge (Bluff, positive)
• Mass standard unit of measure is Newton (N) (Bluff, gram)
• Molecules these are groups of two or more atoms that are chemically bonded. (Fact)
• Chemistry - is a branch of science that deals with atoms, molecules, ions which makes the compounds that are essential for daily life by means of some chemical reactions.
• Matter - is all the “stuff” that exists in the universe. Everything you can see, and touch is made of matter, including you!
• Organic Chemistry - is a study of carbon-based compounds; with a few exceptions like carbon monoxide (CO) and carbon dioxide (CO2). Organic chemistry contains a compound elements carbon and hydrogen. Examples are perfume, glucose, natural gas, detergents, medicine etc.
• Inorganic Chemistry - is a study of compounds that are made of only one or no carbon elements. Examples are sodium chloride (table salt), carbon dioxide, diamond etc.
• Physical Chemistry - The study of the mechanism, rates, and energetics of chemical reactions. It also relies on a lot of physics and math to study the changes in energy that happen in matter.
• Analytical Chemistry - is a study of the quality and quantity of components of substance. In this field the chemist detects and identifies if a substance is present in a sample (qualitative analysis) and how much is in there (quantitative analysis).
• Bio Chemistry - it deals with chemicals processes in living organisms.
• Volume - Can be measures the amount of space that a substance or an object takes up. The basic SI unit for volume is the cubic meter (m3).
• Weight = Neurons
• Mass = Grams
• Atom - These are the smallest particle/unit of matter that cannot be broken down chemically.
• Molecules - These are groups of two or more atoms that are chemically bonded.
• Ions - These are particles that have gained or lost one or more of their valence electrons. There are two types of ions, the CATION is a type of ion with positive charge and those with negative charge are called ANION.
• Solid - Has a fixed volume and shape, high density, difficult to compress
• Liquid - Fixed Volume, shape conforms to the containers, moderate density, minor compressibility
• Gas - Volume and Shape conforms to the containers, low density, easy to compress
• Physical Properties of Matter - This refers to the characteristic or trait of matter that can be observed or perceived with our senses easily without changing its chemical composition
• Intensive - Do not depend on the amount of matter in a sample
• Extensive - Depend how much matter in a sample contains
• Ductility - is the ability of substance to be stretched into wire.
• Malleability - Ability of substance to be hammered or transformed into thin sheet.
• Diffusion - Is the ability of matter to be scattered or spread out.
• Temperature - How cold or hot an object is
• Color - The aspect of any object that may be described in terms of hue, lightness, and saturation
• Brittleness - Describes the property of a material that fractures when subjected to stress
• Volume - The space occupied within the boundaries of an object in three-dimensional space.
• Length - The measurement or extent of something from end to end
• Width - The measurement or extent of something from side to side.
• Mass - Is a dimensionless quantity representing the amount of matter in a particle or object.
• Chemical Properties of Matter - This is the characteristic or trait that can be observed when a matter reacts to another substance.
• Combustibility - The quality of being capable of igniting and burning.
• Flammability - Is a measure of how quickly a specific material can catch fire and burning
• Oxidation Reaction - Reactions in which an element combines with oxygen (exposed in oxygen and moisture)
• Mixture - is a physical blend of two or more components; each of which retains its own identity and properties. The parts or components of a mixture are simply mixed together physically and can usually be separated.
• Homogenous Mixture - is a mixture in which the composition is uniform throughout the mixture.
