|---|---|---|---|---|---|
| Matter | Anything that takes up space or has mass.
🗑
|
||||
| Mass | The material that makes up matter.
🗑
|
||||
| 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 | The smallest part of an Element, a building block of matter.
🗑
|
||||
| electron | A particle of an atom with a negative charge.
🗑
|
||||
| proton | A particle of an atom which is positive energy.
🗑
|
||||
| neutron | A particle of an atom which has no energy it is neutral.
🗑
|
||||
| Periodic Table | Grid that identifies and classifies the Elements into periods and groups by their chemical.
🗑
|
||||
| periods/rows | Provides information for how many energy level, shells that surround.
🗑
|
||||
| groups/columns | Columns that tell how many valence each element has.
🗑
|
||||
| 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 the same # of neutrons and electrons.
🗑
|
||||
| atomic mass | The measurement of the mass for a elements atom.
🗑
|
||||
| chemical property | The ability of substances to combine with each other forming new/ different compounds and molecules.
🗑
|
||||
| physical property | The state of matter/ appearance of a substance.
🗑
|
||||
| ionic bond | When elements either lose or gain a 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/ change.
🗑
|
||||
| compound/ molecule | Two or more elements combined together in a specific ratio/ pattern creating a entirely whole, new and different substance.
🗑
|
||||
| mixture | 2 or more substances combine together keeping their original properties, they don't change into a entirely new substance or compound.
🗑
|
||||
| Nobel Gases | All of the elements in Group #18 they are the most stable elements because they have eight electrons in their own outer shell.
🗑
|
||||
| Halogens | All of the elements in Group #17- have a good reactive bond w/ elements in Group #1, only because they have 7 valence electrons and they 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 change that absorbs energy. Ex: baking soda and vinegar.
🗑
|
||||
| Exothermic | Chemical reaction that releases energy. Ex: sunlight.
🗑
