|---|---|---|---|---|---|
| atoms | smallest piece of matter that retains the properties of the element
🗑
|
||||
| nucleus | very small, very dense center of the atom with a positive charge, contains protons and nuetrons
🗑
|
||||
| proton | subatomic particle found in the nucleus, has a positive charge
🗑
|
||||
| neutron | subatomic particle found in the nucleus, has no electrical charge (neutral)
🗑
|
||||
| electron | subatomic particle that orbits the nucleus, has a negative charge
🗑
|
||||
| quark | subatomic particle that makes up protons and neutrons
🗑
|
||||
| atomic number | number of protons in the nucleus
🗑
|
||||
| atomic mass | the average mass of an atom of an element and all its isotopes
🗑
|
||||
| periods | (Rows) horizontal rows of elements- first element a very reactive solid, last element a very non-reactive gas
🗑
|
||||
| families | (Columns) columns of elements who share similar characteristics
🗑
|
||||
| luster | shininess, high melting point
🗑
|
||||
| malleable | can be pounded into sheets- good conductors
🗑
|
||||
| ductile | can be made into wires
🗑
|
||||
| solid | particles vibrate in place packed tightly together
🗑
|
||||
| liquid | particles are spaced apart more than solids; move moderately fast and flow around each other
🗑
|
||||
| gas | particles move very fast and expand to fit the container
🗑
|
||||
| plasma | state in which matter is heated to extermely high temperature and the electrons separate from atoms
🗑
|
||||
| phase change | when a substance changes from one phase of matter to another due to gain or loss of heat energy
🗑
|
||||
| conservation of matter | matter cannot be destroyed, it can only change forms
🗑
|
||||
| physical property | any characteristic of a material such as a size or shape that you can observe without changing the identity of a material
🗑
|
||||
| matter | solids, liquids, gases, or plasmas
🗑
|
||||
| mass | measure of the amount of matter in an object; always constant
🗑
|
||||
| weight | gravitational force on an object; changes depending on the amount of gravity
🗑
|
||||
| density | the amount of mass in a certain volume; mass/volume
🗑
|
||||
| melting | when a solid changes phase to a liquid due to the addition of heat energy; happens a the melting point
🗑
|
||||
| freezing | when liquid changes to a solid due to a loss of heat energy; happens a the freezing point
🗑
|
||||
| vaporization | when a liquid changes to a gas due to the additon of heat energy; happens at the boiling point
🗑
|
||||
| sublimation | when a solid changes phases to a gas without becoming a liquid due to the addtion of heat energy
🗑
|
||||
| condensation | when a gas changes to a liquid due to a loss of heat energy
🗑
