|---|---|---|---|---|---|
| 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
🗑
|
||||

🗑
|
||||
| What are all the chemical properties we discussed in class? | Reactivity, corrosion, tarnish, radioactivity, oxidation, flammability, pH, rust

| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
