|---|---|---|---|---|---|
| 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 an attractive force that allows it to bond with other atoms
🗑
|
||||
| Proton | particle of an atom located inside the nucleus with a positive charge
🗑
|
||||
| Neutron | no charge located inside the nucleus with the proton/ particle of an atom that is natural
🗑
|
||||
| Periodic Table | a large grid that identifies and classifies all the elements by their chemical and physical properties
🗑
|
||||
| Element | They make up all the matter in the universe/ is the simplest substance that can't be broken down
🗑
|
||||
| periods/rows | tells how many energy levels each element has for the electrons to move around by rows
🗑
|
||||
| Groups or family/columns | columns that shows how many valence electrons each element has / the number of electrons that can move in its outer shell / energy level
🗑
|
||||
| Valence electrons | energy level of an atom / electrons that move on the outer shell
🗑
|
||||
| Atomic number | how many protons an element has inside the nucleus / usually is the same # of neutrons and electrons
🗑
|
||||
| Atomic mass | the measurement of the mass for an elements atom
🗑
|
||||
| Chemical property | the ability of substances to combine with one another forming new and different compounds and molecules
🗑
|
||||
| Physical property | the state of matter and appearance of a substance
🗑
|
||||
| Ionic bond | when elements either lose or gain an electron during bonding
🗑
|
||||
| Covalent bond | when elements share electrons during bonding
🗑
|
||||
| Chemical change / reaction | elements bond together through the attractive force of electrons creating some type of reaction and change
🗑
|
||||
| Compound / molecule | two or more elements combine together in a specific ratio / pattern creating a whole, new and different substance
🗑
|
||||
| Mixture | two or more substances combined together keeping their original properties, they do NOT change into a whole new substance / compound
🗑
|
||||
| Noble gases | all of the elements in group #18 - they are the most stable elements because they have eight electrons in their outer shell
🗑
|
||||
| Halogens | all of the elements in group #17 - the are very reactive bonding easily with elements in group #1 because they have seven valence electrons and want to be stable
🗑
|
||||
| Alkali metals | all of the elements in group #1 - they are very reactive because they have only one valence electrons
🗑
|
||||
| Metalloids | elements between metals and non-metals that 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.
