|
Atomic number |
The whole number on the periodic table. Number of protons and electrons. |
|
|
Atomic mass |
The number in the periodic table with a decimal. Mass=protons/#of neutrons |
|
|
Nucleus |
The center of the atom made up of protons/neutrons |
|
|
Electron shells; period |
The energy level around the nucleus where electrons orbit. |
|
|
Valence ; group |
The number of electrons in the outermost electron shell |
|
|
Mass number |
The rounded atomic mass equal to the number of protons and neutrons. |
|
|
Metals |
Malleable(able to bend,shiny,good conductors of heat and electricity) Left side of periodic table |
|
|
Non-metals |
Brittle(breaks easy, not shiny) poor conductors of heat. Right side of periodic table. |
|
|
Metalloids |
Brittle, dull,good conductors of heat and electricity. Next to to the zig zag on the periodic table. |
|
|
Solids |
Size of a solid doesn't change Shape does not change Solids are most dense Molecules move the slowest Tightly packed together Lowest temperature |
|
|
Liquids |
Size does not change Shape depends on the container Molecules at faster than solid Slower than gases Loosely held together |
|
|
Gases |
Size depends on container Shape depends on the container Molecules move faster than liquids Slower than plasma |
|
|
Plasma |
Size depends on container Shape depends on container |
