Peridiocity
Across
- 2. a column in the periodic table of the chemical elements
- 3. the number of atoms, ions, or molecules that a central atom or ion holds as its nearest neighbor in a complex or coordinate compound
- 4. The horizontal rows of the periodic table
- 7. any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium.
- 10. any of the six chemical elements that make up Group 1 of the periodic table
- 13. any of a series of 15 consecutive chemical elements in the periodic table from actinium to lawrencium
- 14. chemical catalysts whose physical phase is different from the phase of the reactants/products that take part in the catalyzed chemical reaction.
- 15. any of the seven chemical elements that make up Group 18 of the periodic table.
Down
- 1. a process where the reactants involved in the reaction and the catalyst are in the same phase
- 5. the attraction exerted by the nucleus on electrons due to the positive charge of the protons and negative charge of the electron.
- 6. the blocking of valence shell electron attraction by the nucleus, due to the presence of inner-shell electrons.
- 8. any of various metallic elements that have valence electrons in two shells instead of only one
- 9. a table of the chemical elements arranged in order of atomic number in rows and columns.
- 11. any of the six nonmetallic elements that constitute Group 17 of the periodic table
- 12. an ion or molecule attached to a metal atom by coordinate bonding
