Across
  1. 2. an element that lacks most of the properties of a metal; these are found on the right-hand side of the zigzag line on the periodic table
  2. 6. a negatively charged particle found outside the nucleus of an atom
  3. 7. the places surrounding the nucleus of an atom where the electrons are most likely to be at any given time
  4. 9. An element is a pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world
  5. 11. a one- or two-letter representation of an element on the periodic table
  6. 14. a small particle in the nucleus of the atom; it has no electrical charge
  7. 15. the basic particle from which all elements are made
  8. 16. the number of protons in the nucleus of an atom; this number identifies an element and its location on the periodic table
Down
  1. 1. a horizontal row of elements in the periodic table
  2. 3. a chart of the elements showing the repeating pattern of their properties; arranged by atomic numbers of the elements
  3. 4. "a class of elements characterized by physical properties that include shininess
  4. 5. elements in the same vertical column of the periodic table; also known as a 'family'
  5. 8. the central core of the atom made up of protons and neutrons
  6. 10. an element that has some characteristics of both metals and nonmetals; these are found hugging the zigzag line on the periodic table
  7. 12. the average mass of all the isotopes of an element; this is the decimal value found on an element card
  8. 13. a positively charged particle that is part of an atom's nucleus; the number of protons is known as the atomic number
