3. Metals: 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.
5. Any of five related nonmetallic elements (fluorine or chlorine or bromine or iodine or astatine) that are all monovalent and readily form negative ions
6. 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.
9. Earth Elements: These elements are referred to as the lanthanide and actinide series, are all synthetic (man made), and are all metals.
10. Elements that are in the same horizontal row in the periodic table
13. Metals: 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.
14. number of electrons in the outermost energy level
15. Gasses: 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.

1. Materials that can be hammered or rolled into sheets
2. Earth Metals: 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.
4. Elements that are found between the metals and nonmetals, and share similarities with both metals and nonmetals. Most of these are semiconductors.
7. Dot Diagram: uses the chemical symbol of an element surrounded by dots to represent
8. Elements that are similar and found in vertical columns on the periodic table
11. Element: One in which the nucleus breaks down and gives off particles and energy
12. Elements that have similar characteristics
16. Metals: 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.
