Vocab Crossword
Across
- 3. ions ions that are made of more than one atom
- 4. solids a substance in which all of the atoms are covalently bonded to each other
- 6. angle the angle formed by two bonds to the same atom
- 7. consisting of two atoms
- 11. number the positive or negative charge of a monatomic ion
- 12. atom an atom that is located at the end of a molecule or chain
- 13. Valence Shell Electron Pair Repulsion
- 14. Compounds Created by the unequal sharing of electrons. The result is a molecule with a positive end and a negative end. (Ex: water)
- 15. formula Symbols that show the elements in a compound and the ratio of atoms
- 18. A substance made up of atoms of two or more different elements joined by chemical bonds
- 20. Shell Electron Pair Repulsion (VSEPR) Theory each atom in a molecule will move to achieve a geometry that minimizes the repulsion between electrons in the valence shell of that atom. (they will spread out as far as possible)
- 21. structure A structural formula in which electrons are represented by dots; dot pairs or dashes between two atomic symbols represent pairs in covalent bonds.
- 22. der Waals/ London dispersion forces All molecules/compounds have these, temporary dipoles created when electrons move to one side of the atom
Down
- 1. A very large organic molecule composed of many smaller molecules
- 2. attractions between oppositely charged regions of polar molecules
- 5. rule States that atoms lose, gain or share electrons in order to acquire a full set of eight valence electrons
- 8. forces forces of attraction between molecules
- 9. Compounds a compound whose electrons are equally distributed among its atoms (Ex: Oil)
- 10. bonds attractive forces in which a hydrogen covalently bonded to a very electronegative atom is also weakly bonded to an unshared electron pair of another electronegative atom
- 15. atom Atom covalently bonded to one or more atoms in a molecule. The electrons on the central atom determine the shape of the molecule. The least electronegative element
- 16. bond a bond formed by the attraction between positively charged metal ions and the electrons around them
- 17. pair electrons Unbonded electrons that are paired up in an orbital and are not part of a covalent bond
- 18. bond A chemical bond that involves sharing a pair of electrons between atoms in a molecule
- 19. bond A chemical bond resulting from the attraction between oppositely charged ions.
