|---|---|
| Element | |
| Periodic Table of Elements | It represents our understanding of the structure and usefulness of the atoms that have been identified in our environment |
| Metals | shiny, solid at room temperature, highconductivity, can be flattened and not shatter (malleable) |
| Nonmetals | not shiny, mostly gaseous at room temperature, are poor conductors, brittle and will shatter easily(not malleable or ductile) |
| Reactive | Atoms will often take, give, or share electrons with other atoms in order to have a complete set of electrons in their outer energy level. Elements whose atoms undergo such processes are called ______________. Can combine to form compounds |
| Metalloids | have characteristics between metals and nonmetals are solid at room temperature Metals are semi-conductors |
| Atomic Mass | The mass of one atom of the element |
| Atomic Number | Number of protons in one atom |
| Periods/Rows | Each horizontal row of the table |
| Groups/Families | often-but not always-have similar properties. |
| Chemical Symbol | He |
