Across
- 4. formula, represents the covalent bonds as dashes and shows the arrangement of covalently bonded atoms
- 5. covalent bond, two atoms held together by sharing one pair of electrons
- 8. Solids, solids in which all of the atoms are covently bonded to each other.
- 9. compound, a compound composed of molecules
- 12. covalent bond, a covalent bond in which one atom contributes both bonding electrons
- 14. bond, attractive force of a covalently bonded hydrogen to a highly electronegative atom on another molecule.
- 16. Theory, states that the repulsion between electron pairs cause molecular shapes to adjust the electron pairs so they stay as far apart as possible.
