Term | Definition |
Periodic Table | arranges all of the known elements in order of increasing atomic number. Order generally coincides with increasing atomic mass |
Metals | Solid at room temperature |
Metals | Shiny luster |
Metals | Ductile |
Metals | Malleable |
Metals | Good conductors of electricity |
Metals | High Density |
Metals | High melting points |
Metals | Reactivity (those metals at the bottom left corner of the periodic table are most reactive |
Non-Metals | No luster |
Non-Metals | Poor conducter |
Non-Metals | Brittle |
Non-Metals | Not ductile |
Non-Metals | Not malleable |
Non-Metals | Low density |
Non-Metals | Low melting point |
Non-Metals | Less reactive than metals |
Metalloids | Elements on both sides of the zig zag line that have properties of both metals and non metals |
Periods | Rows numbered 1-7 |
Periods | Those in this section have the same number of energy levels or cells |
Periods | Chemical properties are not all similar |
Periods | atomic number increases from left to right |
Groups | A.ka families on the periodic table (coloumns) |
Groups | Same number of valence electrons |
Groups | Chemical properties are very similar |
Chemical reaction | The ability of atoms to combine or separate with other atoms to create new substances |
Reactivity of atoms | Valence Electrons are the key to this process |
Happy/ Stable atoms | Having its outer energy level filled with electrons |
Happy/ Stable atoms | These atoms do not want to bond with other atoms |
Alkali Metals / Alkali Earth Metals | never found uncombined in nature |
Alkali Metals | metals soft enough to be cut with a butter knife |
Alkaline Earth Metals | Fairly reactive metals |
Alkaline Earth Metals | Serve as important minerals for our body |
Transition Metals | Less reactive metals |
Transition Metals | Hard, dense metals that are useful as building materials, jewelry, and coins |
Transition Metals | Used in oxides to make paints and pigments |
Noble Gases | Unreactive gases |
Noble Gases | Do not react naturally |
Nobel Gases | Used in neon signs, baloons, and lightbulbs |
