| Question | Answer |
|---|---|
| element that typically is hard, shiny solid, is malleable, and is a good conductor of heat and electricity | metal |
| ability of metals and alloys to be rolled or hammered into thin sheets | malleable |
| ability of metals to be drawn into wires | ductile |
| occurs because electrons move freely among a metal's positively charged ions and explains properties such as ductility and the ability to conduct electricity | metallic bonding |
| element, such as radium, whose nucleus breaks down and emits particles and energy | radioactive element |
| elements in Groups 3-12 of the periodic table | transition element |
| element that usually is a gas or brittle solid at room temperature, is not malleable or ductile, is a poor conductor of heat and electricity, and typically is not shiny | nonmetal |
| a molecule that conssists of two atoms of the same element | diatomic molecule |
| compound formed when negative ions from an acid combine with positive ions from a base | salt |
| the process of a solid changing directly to a vapor without forming a liquid | sublimation |
| element that shares some properties with metals and some with nonmetals | metalloid |
| different forms of the same element having different molecular structures | allotrope |
| materials having conductivity properties between that of metals (good conductors) and nonmetals (insulators) and having controllable conductivity parameters | semiconductor |
| elements having more than 92 protons, all of which are synthetic unstable | transuranium element |
