Across
- 3. result of the overlap of two parallel electron cloud densities
- 5. Formed when one or more electrons are transferred from one atom to another
- 7. the elements in Group 8A of the periodic table
- 8. One of the elements in Groups 3 through 12 of the periodic table. d block
- 12. Elements that are poor conductors of heat and electric current
- 13. Contains nonmetals, 7 valence electrons in it's outermost energy level. Very reactive
- 14. elements with properties that fall between those of metals and nonmetals
- 16. A negatively charged ion
- 19. any metal in Group 1A of the periodic table
- 20. Elements that are good conductors of electric current and heat.
Down
- 1. A positively charged ion
- 2. a single covalent bond that is formed when an electron pair is shared by the direct overlap of bonding orbitals
- 4. Elements below the body of the periodic table. (Lanthanides and Actinides) f block
- 6. the law that states that the repeating chemical and physical properties of elements change periodically with the atomic numbers of the elements
- 9. A charged atom
- 10. the elements in Group 2A of the periodic table
- 11. a bond formed when atoms share one or more pairs of electrons
- 15. A measure of the ability of an atom in a chemical compound to attract electrons
- 17. The amount of energy required to remove an electron from an atom
- 18. one-half the distance between the nuclei of identical atoms that are bonded together
