Across
  1. 3. An element that has physical and chemical properties of both metals and nonmetals
  2. 4. metal Group 1 elements, except for hydrogen, are reactive & usually exist as compounds with other elements
  3. 6. An ion with a negative charge from gaining electrons
  4. 7. bond A chemical bond resulting from the sharing of valence electrons
  5. 10. An atom or group of atoms with a positive or negative charge
  6. 11. A highly reactive group 17 element with 7 valence electrons
  7. 12. Elements that are generally gases or dull, brittle solids that are poor conductors of heat and electricity
  8. 14. An element that conducts heat and electricity, is lustrous and malleable, tends to be solid
  9. 16. bond The attraction of a metallic cation for delocalized electrons
  10. 18. lattice A 3D geometric arrangement of particles so each ion is surrounded by oppositely charged particles
  11. 19. A vertical column of elements in the periodic table who share chemical and physical properties due to the same number of valence electrons
Down
  1. 1. An ionic compound whose aqueous solution conducts an electric current
  2. 2. An ion with a "pawsitive" charge from losing electrons
  3. 5. bond The electrostatic force that holds oppositely charged particles together in an ionic compound
  4. 8. The smallest particle of an element that retains all the properties of that element, composed of electrons, protons & neutrons
  5. 9. electron The electrons in an atom's outermost orbitals; they determine the chemical properties of an element
  6. 12. gas An extremely unreactive group 18 element with a full valence shell
  7. 13. Formed when two or more atoms share electrons in a covalent bond
  8. 15. A mixture of elements that has metallic properties
  9. 17. Horizontal row of elements in the periodic table
