- 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
- 4. a chemical element that lacks the characteristics of a metal and tends to have a relatively low metal point, boiling point and density
- 7. a distinguishing symbol, such as a letter or numeral, written below or below to the right/left of another character
- 8. atoms of an element with the same number of protons & electrons, but a different number of newtons
- 10. outer shell electrons of the atom that determine an atom’s or group’s ability to bond with others
- 15. outer shell electrons of the atom that determine an atom’s or group’s ability to bond with others
- 19. the horizontal rows of the periodic table
- 22. A neutral charged subatomic particle located in the nucleus
- 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)
- 24. The core of an atom
- 27. a substance composed of exactly two different elements, in which the substances can’t be simplified further by chemical means
- 29. The organized array of all the chemical elements in order of increasing atomic number
- 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
- 33. a chemical element that forms a simple substance and has properties intermediate to typical metals and nonmetals
- 35. A negatively charged ion
- 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
