|---|---|---|---|---|---|
| Matter | anything that has mass and takes up space
🗑
|
||||
| Mass | the material that matter is made of
🗑
|
||||
| Volume | how much room/space matter takes up
🗑
|
||||
| Density | D = m/v the amount of material /stuff matter takes up within a specific space
🗑
|
||||
| Atom | smallest part of an element, the building blocks of all matter
🗑
|
||||
| Electron | particle of an atom that surrounds the nucleus, it has a negative charge and attractive force to bond with other atoms
🗑
|
||||
| Proton | particle of an atoms the positive charge located in the nucleus
🗑
|
||||
| Neutron | particle of an atom the has a neutral / no charge in nucleus and along with proton
🗑
|
||||
| Periodic Table | large table that shows what all elements are and their chemical and physical properties
🗑
|
||||
| Element | simplest substance that makes up everything and cannot be broken down
🗑
|
||||
| Period/Row | how many energy levels has for the electrons to move around for each electron
🗑
|
||||
| Group or Family/Columns | how many valence electrons each element has/ the # of electron to move in outer shell/energy level
🗑
|
||||
| Valence Electrons | electrons that move around in outer shell / energy level of an atom
🗑
|
||||
| Atomic # | # of protons inside the nucleus / normally same # of neutrons and electrons
🗑
|
||||
| Atomic mass | mass for an elements atoms
🗑
|
||||
| Chemical property | substances that combine to create a new substance / compounds and molecules
🗑
|
||||
| Physical property | change in state or appearance
🗑
|
||||
| Ionic bond | element's lose or gain a electron during bonding
🗑
|
||||
| Covalent bond | elements share electrons during bonding
🗑
|
||||
| Compound / molecule | 2 or more combine together in a specific ratio / pattern creating a whole new substance and different
🗑
|
||||
| Mixture | 2 or more substances combined but do not change into a whole new substance
🗑
|
||||
| Nobel Gas | all elements in group have # 18 most stable elements because they have 8 electrons in their outer shell
🗑
|
||||
| Halogens | all elements in group #17 are very reactive bounding with the elements in group #1 because of the seven valence electrons and they want to be stable
🗑
|
||||
| Alkali metals | all elements in group #1 are very reactive because they only have 1 valence electron
🗑
|
||||
| Metalloids | elements between metals and non metals that can react either way they have only one valence electron
🗑
|
||||
| Chemical change / reaction | elements bound through the attractive force of electrons creating reaction / change
🗑

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.
