Mr. Mac Matter/Atom
|anything that has mass, takes up space and is made of atoms
|Matter has properties. These can be...
|size, shape, color, texture, smell, hardness, luster, mass, conductivity, density, volume, magnetism, phase or state, etc...
|What is an atom?
|The smallest unit of matter that retains the properties of that matter. The building block of all matter. A unit of matter consisting of protons, electrons and usually neutrons.
|What are protons?
|The positively charged subatomic particle in an atom's nucleus.
|What are electrons?
|The negatively charged subatomic particles of an atom. They move very quickly in shells or energy levels far away from the nucleus. They are also where chemical bonds for between 2 atoms.
|What are neutrons?
|The subatomic particle in the nucleus of an atom with no charge
|Why did the neutron not have to pay for his drink?
|neutrons have "no charge"
|An electron has been complaining for over an hour. The proton finally tells the electron to...
|"Stop being so negative!"
|A proton calls neutron to tell him he won the lottery. Neutrons says "are you sure?" Proton says...
|To find the number of protons for an atom on the periodic table. You would look at the...
|To find the number of electrons for an atom on the periodic table. You would look at the...
|Atomic number - Atoms like to have there charges balanced.
|To find the number of neutrons for an atom on the periodic table. You would look at the...
|Relative atomic mass and subtract the protons
|What is the atomic number of an atom?
|The number of protons it has.
|What is the relative atomic mass or atomic weight of an atom?
|The average number of protons and neutrons it has.
|Atoms typically have no charge. This is why they will have the same number of...
|protons and electrons.
|This subatomic particle is in energy levels forming the outer layer of an atom.
|Most of the atoms mass is in this part of the atom.
|The nucleons are the...
|protons and neutrons
|A change that in matter that creates a whole new substance with properties that are different from the original, would be a example of which kind of change?
|Baking eggs, flour, butter, milk and sugar makes a cake. The properties of the ingredients changed. This is what kind of change?
|Freezing water changes the physical state of water. This is what kind of change?
|Cutting paper into tiny, tiny little pieces, is what kind of change?
|A protons tells his buddy he is not worried about finding his lost dog. The buddy asks, "why not?" The protons replies...
|"I'm positive... we will find him!"
|A substance that is made of atoms with the same number of protons is...
|A substance that is made of MORE than one kind of atom BONDED together is...
|What is a bond?
|A chemical connection ...made when atoms share electrons (water)
|What is a mixture? How is it different from a compound?
|In a mixture the different atoms have NOT bonded and can be separated.
|Are there different kinds of Mixtures?
|Yes, A solution is a special mixture in which one substance dissolves in another. It can still be separated and no bonds have formed.
|Matter that has a definite shape AND amount of space it takes up is...
|The measurement for the amount of space something takes up is called...
|Matter with no definite shape OR volume is...
|Matter with no definite shape but a definite volume is...
|Which physical state of matter would use all the space in a glass jar no matter how much you had?
|Which states of matter allow the atoms and molecules to flow? (fluid)
|liquid and gas -Yes, gas is a fluid!
|In which state do the molecules or atoms only vibrate?
|Element number 4 is....
|Element number 9 is...
|What are atoms made of?
|electrons, protons and neutrons
|Electrons are located where?
|far away from the nucleus in energy levels or shells.
|Where is the mass of an atom located? Why?
|The nucleus because electrons are almost 2000 times less massive than protons and neutrons.
|Name a compound (molecule) containing Hydrogen.
|Water (H20) Sugar (C6H12O6) Hydrochloric Acid (HCl) Ammonia (NH3) Methane (CH4)
|If an element in its solid state has reached it's melting point it will start to turn into...
|If an element is below it's melting point it will be in what phase/state?
|If Nitrogen's boiling point is -195°C or -320°F, what phase/state will it be at 32°F?
|If Nitrogen's boiling point is -195°C or -320F, What temperature would you need to make it a liquid?
|lower than 195°C or 320°F
|In general, all matter will expand when you increase...
|the temperature (molecular movement)
|Who's experiment discovered that atoms had a positive "proton" and that atoms were mostly empty space?
|Ernest Rutherford ... in his famous gold foil alpha particle experiment.
|Who discovered the electron and that it had a negative charge?
|Can you tell how many atoms the compound rust (Fe2O3) has?
|5 (2 iron atoms and 3 oxygen atoms)
|A molecule is more than one ___________ joined together.
|A compound is more than one different ____________ joined together.
|All compounds are molecules but all ________________ are NOT compounds.
|The law of conservation of mass says, "That during a chemical reaction/change mass is...
|...neither lost nor gained (if you start with 10 atoms - you end with 10 atoms)
|Draw a Bohr model of Na (sodium)
|Did you put 11 protons in the nucleus? Did you put 12 neutrons in the nucleus? Did you draw 3 electron levels/shells? Did the 1st level have 2 electrons, the second have 8 and the third have 1? If YES to all the above, GREAT you did it!
|What kind of property is color?
|What kind of property is texture?
|What kind of property is rotting?
|What kind of property is luster (shiny)?
|What kind of property is burning?
|What are properties of matter?
|the characteristics, attributes, traits that make matter what it is!
|What is the most common state of matter in the universe?
|Plasma - Stars are made of matter in a Plasma State!
|What are words similar to properties? (When referring to matter)
|traits, characteristics, qualities,
|What is anything that can be observed about matter?
|What 2 things dictate the state that matter will be.
|Temperature and Pressure
|Matter will change states only if the ____________________ and ___________________ are correct.
|Pressure and Temperature
|What kind of change is more easily reversed?
|What kind of change is hard or even impossible to reverse?
