|
||||
|---|---|---|---|---|---|
| Element | The basic building blocks of matter
Combine to make other types of matter
Cannot be separated into parts by chemical means
ex: gold, found in nature
🗑
|
||||
| Matter | Anything that has mass and occupies space
🗑
|
||||
| Mass | The amount of matter in an object
Mass affects the weight of an object, but mass is not the same as weight
ex: mass never changes, weight does
🗑
|
||||
| Graduated Cylinder | Use to find the volume of a liquid
Use to measure the volume of a solid object that fits in the cylinder and sinks in water
🗑
|
||||
| Density | d=mass/volume g/cm3 (calculator)
The mass of a substance divided by its volume
Measure of the amount of matter in a given volume
🗑
|
||||
| Neutron | No electrical charge - Neutral
A particle with no electrical charge in the nucleus of an atom
🗑
|
||||
| Nucleus | Protons + Charge (positive)
Contains DNA which controls how the body grows and changes
🗑
|
||||
| Rows | Elements are arranged in each row according to the number of protons
Larger atoms are on the right side of each row
🗑
|
||||
| Symbol | Every element has a symbol of one, two, or three letters
Only the first letter of the symbol is capitalized
🗑
|
||||
| Compound | A substance made up of a combination of two or more elements
Held together by chemical bonds that cannot be separated by physical means
🗑
|
||||
| Physical Properties | Can be observed, described, and measured with tools
mass, volume, phase at room temp, hardness, crush ability, color, texture, odor, bendable, size, shape, able to be cut
🗑
|
||||
| Chemical Properties | Describe how a material changes into another material
ex: wood into ashes, burn wood
🗑
|
||||
| Balance | Tool to measure the mass of an item
Put the item on one side and add gram cubes to the other side until the 2 sides balance
Find the total mass of the gram cubes
Each gram cube has a mass of 1 gram
🗑
|
||||
| Displacement | Occupation by a submerged body of a volume that would otherwise be occupied by a fluid
🗑
|
||||
| Buoyancy | sink or float?
water = density 1.0
< 1 will float
> 1 will sink
🗑
|
||||
| Proton | A positively charged particle in the nucleus of an atom
🗑
|
||||
| Periodic Table of Elements | Table displays chemical elements
Classifies and compares chemical behavior
🗑
|
||||
| Columns | Columns of the table are arranged so that the elements in each column have similar chemical properties
You can predict the properties of an element if you know its column
🗑
|
||||
| Element Number | Atomic number
🗑
|
||||
| Chemical Formula | Shows how many atoms of each element are in the compound
🗑
|
||||
| Metals | Metals such as gold silver copper iron & nickel are elements
Many metals are alloys or mixtures of elements
ex: Steel is a mixture of iron and carbon, Brass is a mixture of copper and zinc, Bronze is a mixture of metals, mostly copper and tin.
🗑
|
||||
| Weight | Measure of the pull of gravity on an object
Measure objects weight in newtons
🗑
|
||||
| Volume | l x w x h (metric ruler) cm3
displacement (grad cylinder) 1 ml = 1 cm3
amount of matter that it can hold
amount of space an object takes up
🗑
|
||||
| Atom | The smallest particle of an element
Has all the properties of the element
🗑
|
||||
| Electron | A negatively charged particle moving around the nucleus of an atom
🗑
|
||||
| Element | One kind of atom, pure
The basic building blocks of matter
Cannot be separated into parts by chemical means
🗑
|
||||
| Molecule | Made up of two or more different kinds of elements (atoms)
ex: Water - H2O (2) Hydrogen + (1) Oxygen
ex: Carbon Dioxide - CO2 (1) Carbon + (2) Oxygen
🗑
|
||||
| Solubility | Dissoluability
solute + solvent
🗑

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.
