---|---|---|---|---|---|
matter | anything that takes up space and has mass
🗑
|
||||
mass | the material that matter is made up of
🗑
|
||||
volume | how much room/space matter takes up
🗑
|
||||
density | D=m/v the amount of material/stuff mass 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 to bond with other atoms
🗑
|
||||
proton | particle of an atoms that positive charge located in the nucleus
🗑
|
||||
neutron | particle of an atom with a neutral/no charge located in the nucleus along with the proton
🗑
|
||||
Periodic Table | large grid that identifies and classifies all of the elements by their chemical and physical properties
🗑
|
||||
element | the simplest substance that cannot be broken down, they also make up all the matter in the universe
🗑
|
||||
periods/rows | rows that tell how many energy levels each elements has for the electrons to move around
🗑
|
||||
groups or families/columns | columns that tell how many valence electrons each element has/ the number of electrons that can move in its outer shell/ energy levels
🗑
|
||||
valence electrons | the electrons that move on the outer shell/ energy level of an atom
🗑
|
||||
atomic number | how many protons an element has inside the nucleus/ usually is the same # of electrons and neutrons
🗑
|
||||
atomic mass | the measurement of the mass for an element's atoms
🗑
|
||||
chemical property | a whole new substance that is irreversible and has a reactivity
🗑
|
||||
physical property | the appearance, size,shape,texture stays the same substance
🗑
|
||||
ionic bond | when elements either gain or lose an electron during bonding
🗑
|
||||
covalent bond | when elements share electrons during bonding
🗑
|
||||
chemical change/reaction | elements bond together due to an 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 elements combine together keeping their original properties, they DO NOT CHANGE into a new substance
🗑
|
||||
nobel 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- they are very reactive bonding easily with elements in Group 1 because they have 7 valence electrons nad want to be stable
🗑
|
||||
alkali metals | all of the elements in GROUP 1- they are very reactive because they have only one valence electron
🗑
|
||||
metalloids | elements between metals and non metals that can react either way, they have 3-7 valence electrons
🗑
|
||||
endothermic | Chemical reaction that absorbs energy
🗑

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.
