Periodic Table metals
| 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 |
