Chemistry
Across
- 4. Number Number of protons
- 8. A mix of multiple different metals
- 9. State of matter. Attraction between particles holds them in a shape very strongly. Particles vibrate.
- 10. Anything that has mass and takes up space
- 12. A particle (atom) with either a positive (Cation) or negative (Anion) charge.
- 13. State of matter. Particles move fast. Flow out of the container.
- 14. Substance containing one type of particle. Two types: Element and compound.
- 15. Group/Family/Column on the Periodic Table. Very unreactive because it has full valence shells. Colourless gases at room temperature.
Down
- 1. A table that lists the known elements in row (period) and columns (group/family).
- 2. Has an atomic number of 8 on the periodic table. Needed for breathing.
- 3. First element of the periodic table and the Alkali Metals
- 4. Group/Family/Column on the Periodic Table. Shiny, soft, malleable, low melting point. One valence electron.
- 5. Has an atomic mass of about 15.9994
- 6. The symbol is Al on the periodic table
- 7. Group/Family/Column on the Periodic Table. 7 valence electrons. Fluoride, Chlorine, Bromine, Iodine, Astatine.
- 11. State of matter. Particles move a little, and take the shape of its container.
