  1. 2. an element that has physical and chemical properties of both metals and nonmetals
  2. 4. group 1 elements, except for hydrogen, are reactive and usually exist as compounds with other elements
  3. 8. elements from groups 1, 2, and 13-18 in the modern periodic table, possessing a wide range of chemical and physical properties
  4. 11. a type of group B element that is contained in the f-block of the periodic table and is characterized by a filled outermost orbital, and filled or partially filled 4f and 5f orbitals
  5. 13. elements that are generally gases or dull, brittle solids that are poor conductors of heat and electricity
  6. 14. a vertical column of elements in the periodic table arranged in order of increasing atomic number; also called a family
  7. 15. in groups 3-12 of the modern periodic table, which are further divided into transition metals and inner transition metals
Down
  1. 1. group 2 elements in the modern periodic table are highly reactive
  2. 2. an element that is solid at room temperature, a good conductor of heat and electricity, and generally is shiny; most metals are ductile and malleable
  3. 3. in the periodic table, the f-block elements from period 7 that follow the element actinium
  4. 5. in the periodic table, the f-block elements from period 6 that follow the element lanthanum
  5. 6. a horizontal row of elemerepresentativeodic table
  6. 7. an element in groups 3-12 that is contained in the d-block of the periodic table and, with some exceptions, is characterized by a filled outermost s orbital of energy level n, and filled or partially filled d orbitals of energy level n − 1
  7. 9. an extremely unreactive group 18 element
  8. 10. states that when the elements are arranged by increasing atomic number, there is a periodic repetition of their properties
  9. 12. a highly reactive group 17 element
