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