|---|---|---|---|---|---|
| matter | everything that has mass and takes up space
🗑
|
||||
| mass | the material matter is made of
🗑
|
||||
| volume | the space matter takes up
🗑
|
||||
| density | the amount of mass in a specific volume of space
🗑
|
||||
| atom | the smallest element and the building block for all matter
🗑
|
||||
| electron | the particle of an atom with a negative charge, moves around the nucleus and has an attractive force which allows it to bond with other atoms
🗑
|
||||
| proton | particle of an atom located in the nucleus with a positive charge
🗑
|
||||
| neutron | particle of an atom without a charge located inside the nucleus
🗑
|
||||
| periodic table | large grid that organizes all elements by physical and chemical properties
🗑
|
||||
| element | the simplest substances that cannot be broken down
🗑
|
||||
| periods/rows | rows tell how many energy levels each elements have for electrons to move around
🗑
|
||||
| groups or family/columns | columns show valence electrons/the number of electrons that can move on its outer shell
🗑
|
||||
| valence electrons | electrons that move on outer shell
🗑
|
||||
| atomic number | how many protons an elements has inside the nucleus
🗑
|
||||
| atomic mass | the measurement of the mass for an elements atoms
🗑
|
||||
| chemical property | the ability of substances to combine with each other forming new compounds and molecules
🗑
|
||||
| physical property | the state of matter and appearance
🗑
|
||||
| ionic bond | when elements lose or gain and electron during bonding
🗑
|
||||
| covalent bond | when elements share electrons during bonding
🗑
|
||||
| chemical change | elements bond through an attractive force of electrons creating some type of reaction and change
🗑
|
||||
| compound/molecule | two or more elements combine together in a set ratio creating a whole new substance
🗑
|
||||
| mixture | two or more substances together but keeping there original properties they don't change into a new substance
🗑
|
||||
| Nobel gases | all elements in group #18 they are most stable cause they have 8 electrons in their outer shell
🗑
|
||||
| halogens | all elements in group #17 they are reactive bonding easily with elements in group 1 cause they have 7 valence electrons and want to be stable
🗑
|
||||
| alkali metals | all elements in group #1 they are very reactive because they only have one valence electron
🗑
|
||||
| metalloids | elements between metals and non metals can react either way, they have 3-7 valence electrons
🗑

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.
