States Of Matter
What are the 4 States of Matter?
Solid, Liquid, Gas, and Plasma
What are Period Trends?
They are specific patterns that show up on the Periodic Table.
What is physical change?
Matter changes that form but not chemical identity.
What are two Redox Reactions?
Reduction and Oxidation.
What is Acid and Base Solutions?
A physical property that is a characteristics of matter that can be observed or measured without changing the identity of the matter.
What does a Solid do?
Solids are Tightly Pressed Together.
What is Electronegativity?
A chemical property that describes an atom's ability to attract and bond with electrons.
What is Chemical Change?
A chemical reaction that forms new products.
What is Reduction?
To gain an electron.
What are Acids?
A substance that promotes a chemical change and create salt water with a base.
What does a Liquid do?
Liquids are Close Together, but not as tightly packed as a solid.
How do atoms interact with other atom's electrons?
This depends on how many electrons an atom has on it's outer shell.
What are 3 examples of a Physical Change?
Melting Ice, Boiling Water, and cutting paper.
What is Oxidation?
To lose electrons.
What are Bases?
Any substance that causes chemical change and creates salt water with an acid.
What does a Gas do?
Gases are Far Apart, so they have a large range of motion and they often collide with each other.
How many atoms form to bond in order to complete their outer shell?
8 electrons.
What are 3 examples of a Chemical Change?
Burning Wood, Rusting Iron, and Baking a Cake.
Why is keeping track of these oxidation states important?
Oxidation States are important as they help us keep track of where each electron is moving in a compound.
What is a pH scale?
A measure of how acidic or basic water is.
What does Plasma do?
Plasma's are very high temperature, so that high temperature causes electrons to leave their shells and Float Around.
What do atoms form to make a perfect octet?
They will gain or lose electrons.
Is Burning paper Physical or Chemical?
Chemical Change.
How do we know the oxidation state/number of elements?
The Oxidation State of any atom that is completely individual is 0.
What is a pH Indicators?
Can be used to measure the approximate pH of a solution.
