Mr. Mac Matter/Atom
| Question | Answer |
|---|---|
| Matter is... | 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... | "I'm positive!" |
| To find the number of protons for an atom on the periodic table. You would look at the... | Atomic Number |
| 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. | electron |
| Most of the atoms mass is in this part of the atom. | The Nucleus |
| 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? | Chemical |
| Baking eggs, flour, butter, milk and sugar makes a cake. The properties of the ingredients changed. This is what kind of change? | Chemical |
| Freezing water changes the physical state of water. This is what kind of change? | Physical |
| Cutting paper into tiny, tiny little pieces, is what kind of change? | Physical |
| 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... | an element |
| A substance that is made of MORE than one kind of atom BONDED together is... | a compound |
| 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... | a solid |
| The measurement for the amount of space something takes up is called... | volume |
| Matter with no definite shape OR volume is... | gas |
| Matter with no definite shape but a definite volume is... | liquid |
| Which physical state of matter would use all the space in a glass jar no matter how much you had? | gas |
| 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? | solid |
| Element number 4 is.... | Beryllium |
| Element number 9 is... | Fluorine |
| 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... | a liquid |
| If an element is below it's melting point it will be in what phase/state? | solid |
| If Nitrogen's boiling point is -195°C or -320°F, what phase/state will it be at 32°F? | Gas |
| 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? | JJ Thompson |
| 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. | atom |
| A compound is more than one different ____________ joined together. | element |
| All compounds are molecules but all ________________ are NOT compounds. | molecules |
| 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? | Physical |
| What kind of property is texture? | Physical |
| What kind of property is rotting? | Chemical |
| What kind of property is luster (shiny)? | Physical |
| What kind of property is burning? | Chemical |
| 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? | Property |
| What 2 things dictate the state that matter will be. | Temperature and Pressure |
