Nov 4th Test Review

Review for Density, Mineral Identification, & Periodic Table Elements

QuestionAnswer
What element is found in the atmosphere, ocean, Earth's crust, and the human body? Oxygen
What are clues that a chemical change occurred? Unexpected color change, odor change, release of light, release of heat, release of sound, produces a gas, produces water, forms a precipitate (a solid), creates a new substance with new properties
What type of elements are located on the left side of the periodic table? metals
What is the chemical symbol for Nitrogen? N
When we identify minerals, we describe luster. What is luster? Luster is the way a mineral reflects or absorbs light. Luster can be metallic or nonmetallic (adamantine, resinous, vitreous, or pearly).
When we identify minerals, we use a streak plate. What is the streak of a mineral? Streak is the powdery residue a mineral leaves behind when rubbed across an unglazed porcelain streak plate.
What properties are MOST helpful in identifying a mineral? HINT: What properties do not change with the size of the sample? Density, streak, hardness, and luster
What group of elements are located on the right side of the periodic table? nonmetals
What elements are located along the zigzag or stair-step lined of the Periodic Table? metalloids
What are characteristics of metals? Metals are malleable, shiny, ductile, thermal conductors, electrical conductors, and are located on the left side of the Periodic Table.
What are characteristics of nonmetals? Nonmetals DO NOT have metallic properties. They are located on the right side of the Periodic Table. They have a dull luster and solid nonmetals are brittle. They are also good insulators.
What are characteristics of metalloids? Metalloids are located along the zigzag or stair-step line of the Periodic Table. Metalloids are good semiconductors. Metalloids have some properties of metals and some properties of nonmetals.
Horizontal rows (from left to right) on the periodic table are called ________________ periods
Vertical columns (up and down) on the periodic table are called ____________________ groups
How many periods (rows) are on the Periodic Table? 7
How many groups (columns) are on the Periodic Table? 18
How can you tell the difference between an atom, a molecule, and a compound? An atom is the smallest particle of matter. A molecule contains two or more atoms bonded together. A compound is a molecule with two or more atoms of DIFFERENT elements bonded together.
What is the density of an object with a mass of 24 g and a volume of 6 mL? 4 g/mL
How do you calculate density? Density = mass/volume
What equipment is used to measure mass? a balance
What equipment is used to measure volume of liquids? a graduated cylinder
What equipment is used to measure volume of solids? metric ruler or meter stick
What is the density of an object with a mass of 50 g and a volume of 25 mL? 2 g/mL
List all the physical properties we discussed in class Melting point, boiling point, density, hardness, magnetism, malleability, viscosity, state of matter, ductility, luster, solubility, texture, thermal conductivity, electrical conductivity
What are all the chemical properties we discussed in class? Reactivity, corrosion, tarnish, radioactivity, oxidation, flammability, pH, rust
Elements in the same column (or group) have similar ___________ properties
Elements on the periodic table are labeled with a chemical _____________ symbol
Compounds are labeled with a chemical ______________ formula
Rusting is an example of a _____________________ change chemical
Cutting an apple is an example of a _________________ change physical
Melting butter is an example of a ___________________ change physical
