Across
- 3. A table of the chemical elements arranged in a way that displays their periodic properties in relationship to their atomic numbers.
- 5. A row on the periodic tables
- 7. The elements in Group 1 and they have one valence electron
- 8. The two rows of elements shown below the main body on most periodic tables
- 9. These elements typically have four or more valence electrons and do not exhibit the general properties of metals.
- 10. These elements have characteristics between those of metals and nonmetals and located along the stairstep line and are also called semiconductors.
Down
- 1. Consists of elements from Group 17 and these elements each have seven valence electrons.
- 2. Set of elements in the same column on the periodic table
- 4. Groups 13–16 contain metals, nonmetals, and metalloids.
- 6. The electrons in the outermost energy level of a neutral atom.
