Across
  1. 2. a notation used by scientists to show the number and type of atoms present in a molecule, using the atomic symbols and numerical subscripts
  2. 4. a chemical element that lacks the characteristics of a metal and tends to have a relatively low metal point, boiling point and density
  3. 7. a distinguishing symbol, such as a letter or numeral, written below or below to the right/left of another character
  4. 8. atoms of an element with the same number of protons & electrons, but a different number of newtons
  5. 10. outer shell electrons of the atom that determine an atom’s or group’s ability to bond with others
  6. 15. outer shell electrons of the atom that determine an atom’s or group’s ability to bond with others
  7. 19. the horizontal rows of the periodic table
  8. 22. A neutral charged subatomic particle located in the nucleus
  9. 23. a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds(this can be an ionic bond or a covalent bond)
  10. 24. The core of an atom
  11. 27. a substance composed of exactly two different elements, in which the substances can’t be simplified further by chemical means
  12. 29. The organized array of all the chemical elements in order of increasing atomic number
  13. 32. a substance when two or more chemical elements are chemically bonded together, there are two common types of bonds holding elements together in a compound which are covalent and ionic
  14. 33. a chemical element that forms a simple substance and has properties intermediate to typical metals and nonmetals
  15. 35. A negatively charged ion
  16. 36. a type of linkage formed from the electrostatic attraction between oppositely charged ions in a physical compound, this bond forms when the valence electrons of an atom are permanently transferred to another atom
Down
  1. 1. A positively charged ion
  2. 3. an atom that has gained electrons, giving it a negative ions
  3. 5. an element that readily forms cations and has metallic bounds
  4. 6. The total number of protons and neutrons, which are located in the nucleus
  5. 9. The area/region of electrons surrounding the nucleus in an atom
  6. 11. The total number of protons of an atom
  7. 12. The smallest unit of matter
  8. 13. a compound composed of ions of two different elements, one a metal and another a nonmetal
  9. 14. Specific patterns in the properties of chemical elements
  10. 16. a group of atoms bonded together, showing the smallest fundamental unit of a chemical compound that may take part in a chemical reaction
  11. 17. the interatomic linkage that comes from the sharing of an electron pair between two atoms, in which the binding arises from the electrostatic attraction of their nuclei for the same electrons
  12. 18. the vertical columns of the periodic table
  13. 20. the arrangement of electrons in energy levels around an atomic nucleus
  14. 21. A negatively charges subatomic located in the electron- cloud

  16. 26. an atom that has lost electrons, giving it a positive charge
  17. 28. also called a group, is a column of elements in the periodic table of elements
  18. 30. a physically distinctive form of matter( such as a solid, liquid, gas, or plasma) and is characterized by having relatively uniform chemical and physical properties
  19. 31. A positively charged subatomic particle that is located in the nucleus of an atom
  20. 34. The total mass of an atom
