| Question |
Answer |
| Physical Property |
any property of a substance that can be observed without a change in the substance. |
| Chemical Property |
any property of a substance that is observed during a chemical change. |
| qualitative |
comparison based on qualities that determine the chemical constituents of the substance or mixture. |
| quantitative |
determines the amounts and proportions of the chemical constituents of a substance or mixture. |
| Physical Change |
any change in matter where no new substance is formed. |
| Chemical Change |
Any change in matter in which at least one new stubstance is formed. |
| Pure Substance |
Cannot be seperated physically, and is made of only one type of matter. |
| Mixture |
A substance that is made up of more than one type of matter, and can be physically seperated. |
| Element |
Pure substance that cannot be further broken down. Contains a single type of atom. |
| Compound |
Contrains two or more different types of atoms and can be further broken down into their contituent elements. |

heterogeneous mixture |
| What is another name for a solution |
homogeneous mixture |
| Mechanical Mixture |
A mixture that contrains particles that are not uniformly distributed, and are visually distinguishable. |
| Solution |
A mixutre that contains particles that are uniformly distributed, and are visually distinguishable |
| Atom |
is the smallest form of matter. |
| Nucleus |
The central control organelle of a cell. |
| atomic number |
The number of protons in the nucleus of an atom. |
| mass number |
the number of protons and neutrons in the nucleus of an atom. |
| proton |
positively charged particle in the nucleus |
| neutron |
neutral particles in the nucleus |
| electron |
negatively charged particles, orbating outside of the nucleus of the atom. |
| isotopes |
atoms of the same element with the same number of protons but a different number of neutrons. |
| metal |
a substance with a shiny appearance, good conductability of electricity and heat. Malleable and Ductile. |
| malleable |
capable of being beaten out bent or shaped. |
| ductile |
capable of being stripped to wires. |
| conductivity |
the ability to transmit light, electricity, heat or sound. |
| non-metal |
