Across
- 4. element or substance that is not a metal.
- 5. Chemically they show variable valence and a strong tendency to form coordination compounds, and many of their compounds are colored.
- 8. elements, when listed in order of their atomic numbers fall into recurring groups, so that elements with similar properties occur at regular intervals.
- 10. metals chemical compound that neutralizes or effervesces with acids and turns litmus blue
Down
- 1. reactive, electropositive, divalent metals, and form basic oxides which react with water to form comparatively insoluble hydroxides.
- 2. elements where the s and p orbitals are filling
- 3. an element whose properties are intermediate between those of metals and solid nonmetals or semiconductors.
- 6. gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table.
- 7. solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity
- 9. reactive nonmetallic elements that form strongly acidic compounds with hydrogen from which simple salts can be made.
