Across
- 2. Elements that are in the same horizontal row in the periodic table
- 5. Elements that are soft and shiny, highly reactive with other elements, lose their outermost electron, and can be cut easily. These elements are only found in salts.
- 8. These metals do not share characteristics with any other metals, highly malleable and ductile, and have a semi-high density. These elements are also solid at room temperature.
- 10. Elements that are malleable and ductile, are good conductors of heat and electricity, and are very dense. These elements have a high melting and boiling point.
- 11. These elements do not conduct heat or electricity well, are very brittle, do not reflect light, and have low shine. Oxygen and Carbon are Non-Metals.
- 14. that can be hammered or rolled into sheets
- 15. Elements that are similar and found in vertical columns on the periodic table
Down
- 1. These elements are very stable, almost never react with other elements, are all gasses, and are odorless and colorless. They also have a very low melting and boiling point.
- 3. These elements are referred to as the lanthanide and actinide series, are all synthetic (man made), and are all metals.
- 4. uses the chemical symbol of an element surrounded by dots to represent the number of electrons in the outermost energy level
- 6. Elements that are shiny and silvery-white, are only somewhat reactive with elements, and easily lose their two outermost electrons. These elements have low density, low melting points, and a low boiling point.
- 7. Any of five related nonmetallic elements (fluorine or chlorine or bromine or iodine or astatine) that are all monovalent and readily form negative ions
- 9. One in which the nucleus breaks down and gives off particles and energy
- 12. Elements that are found between the metals and nonmetals, and share similarities with both metals and nonmetals. Most of these are semiconductors.
- 13. Elements that have similar characteristics
