Across
- 2. Materials that readily conduct an electric current
- 4. Two or more atoms of same or different kinds chemically bonded together.
- 5. The way a substance reflects light.
- 7. Refers to the electron configuration outside the nucleus of an atom.
- 10. The simplest form of a molecule made of only one type of atom with a certain number of protons and properties unique to that element.
- 11. Elements found along the zig-zag of the periodic table that share properties of both metals and non-metals.
Down
- 1. Numbered columns of the periodic table. Numbers correlate with the number of valence electrons for a neutral atom.
- 3. Physical property of metals and metalloids. Malleable metals can easily be deformed, especially by hammering or rolling, without cracking.
- 6. States that mass cannot be lost or gained. Therefore, the number of atoms and mass at the beginning of a reaction must equal the number or atoms and mass at the end of a reaction.
- 8. A subatomic particle, with a negative charge, found outside the nucleus of an atom.
- 9. Elements located to the left of the zigzag line on the periodic table. Generally, these are good conductors, reactive and have shiny luster.
