Across
- 3. compound is something consisting of precisely two elements.
- 5. a molecule, made from joining together many small molecules called monomers.
- 7. pair an electron pair in the outermost shell of an atom that is not shared or bonded to another atom.
- 10. ion an ion that has two or more covalently bonded atoms that act as a single ion.
- 13. formula a notation used by scientists to show the number and type of atoms present in a molecule, using the atomic symbols and numerical subscripts
- 14. compound is any member of a large class of gaseous, liquid, or solid chemical compounds whose molecules contain carbon.
- 15. bond electrons are shared unequally, the more electronegative atom's pull is stronger
- 16. compound made when two or more nonmetal atoms bond by sharing valence electrons.
- 19. bond a chemical bond in which three pair of electrons is shared between two atoms.
Down
- 1. bond a chemical bond in which two pairs of electrons are shared between two atoms.
- 2. energy defined as the amount of energy required to break apart a mole of molecules into its component atoms.
- 4. bond type of bond that occurs when two atoms share a pair
- 6. made up two or more atoms chemically joined together.
- 8. is the property of an atom which increases with its tendency to attract the electrons of a bond.
- 9. element is a molecule of an element consisting of two atoms.
- 11. Structure a diagram that shows the covalent bonds and lone electron pairs in a molecule.
- 12. bond a chemical bond in which one pair of electrons is shared between two atoms.
- 17. Rule refers to the tendency of atoms to prefer to have eight electrons in the valence shell.
- 18. theory is a model used to predict the geometry of molecules based on minimizing the electrostatic repulsion of a molecule's valence electrons around a central atom.
