| Term | Definition |
|---|---|
| matter | Anything that has mass and volume |
| physical properties | the characteristics of a substance such as density, volume, phase and color |
| conductivity | something that allows a charge to travel through it |
| malleability | defined as being able to hammer it into sheets, like a sheet of aluminum |
| chemical properties | the ability of a substance to react with other substances and create a new substance, or its flammability |
| flammability | the ability to light on fire or to combust |
| reactivity | the ability to combine with other atoms or compounds creating a new substance |
| chemical change | the process where a substance changes to produce a new substance, this may not be a reversible change |
| physical change | a change in appearance, phase or shape would be what type of a change |
| states of matter | Describing how much energy is in a substance therefore describing the arrangements of atoms into a solid, liquid or a gas |
| compound | two different atoms chemically combined together |
| mixture | a combination of 2 or more substances but they are not chemically bound together |
| element | a substance that can't be broken down or separated into a simpler substance by a chemical means |
| heterogeneous | in mixtures, this is when the mixture is not uniform and does not mix readily |
| homogeneous | in mixtures this is when the mixture is uniform and mixes very well |
| colloid | tiny suspended particles in a mixture, like in milk. |
| isotope | when the number of neutrons change in an element it will create... |
| Bose-Einstein solid, solid, liquid, gas, plasma | What are the phases of matter from coldest to hottest? |
| solution | a mixture of two substances that mix up really well and are dispersed homogeneously throughout |
| solubility | a property of a substance where it has the ability to be dissolved given the correct situation (temperature,and pressure) |
| solute | in a mixture the item that was broken down and dissolved is called the... |
| solvent | in a mixture, the substance that will dissolve something else |
| atomic name | each symbol of letters on the periodic table represents what... |
| plasma | a super heated substance beyond a gas that would seem to emit light, like the sun |
| organic | CHONPS....if a compound has these (they are written in order of importance) then they are what...? |
| inorganic | compounds or elements that have never been alive or part of a living thing such as mined minerals |
| half life | The time required to decay an element from 100% of itself to 50% of itself. |
| Strong, Weak, electromagnetic, gravitational | What are the forces inside of an atom? |
| -+ = Electromagnetic, weak is decay, Strong force keeps nucleus together in spite of + next to a +, gravity is mass and distance to that mass. | Explain each of the forces in an atom |
| Nucleus | contains the protons and neutrons and is where the atom has mass |
| Orbitals or Shells | the location of the electrons that surround the nucleus |
| valence shell | the outermost ring of electrons that give the atom the ability to bond |
| Do | Draw a correct atom with its 3 primary parts labeled Use #9 Flourine BSD St 5-01 |
| Count the protons and neutrons, use periodic table | Find the mass of an atom |
| change the number of neutrons | Make an isotope of an atom |
| Law of conservation of matter. | Matter can be neither created nor destroyed. |
| Go figure this out! Think about the steel wool lab... | Prove the law of conservation of matter using a short answer. |
