Across
- 3. mass/ The mass in grams of one mole (or 6.02 x 1023 molecules) of any chemical compound.
- 4. mass/ the sum of atomic weights of the atoms in a molecule
- 5. length/ the average distance between nuclei of two bonded atoms in a molecule
- 7. composition/ Usually means percent composition by mass. Could also be percent composition by mole, or by weight.
- 9. formula/ a chemical formula based on analysis and molecular weight.
- 10. bond/ a chemical bond in which one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion.
- 12. a method of describing the delocalized electrons in some molecules where the bonding cannot be explicitly expressed by a single Lewis structure
- 15. bond/ A chemical bond in which three pairs of electrons are shared between two atoms.
- 17. covalent bond/ a bond in which one nucleus of an atom donates both electrons to form a bond with another atom
- 18. hybridization/ mixing atomic orbitals to form new hybrid orbitals suitable for the qualitative description of atomic bonding properties.
- 19. rule/ atoms that tend to combine in such a way that they each have eight electrons in their valence shells
Down
- 1. bond/ A real fancy way of saying "single bond"
- 2. number/ The number of atoms or molecules in one mole of a substance
- 3. The mole is a unit of measurement for the amount of substance or chemical amount.
- 6. bond/ A chemical bond in which two pairs of electrons are shared between two atoms.
- 8. ion/ An ionic species containing more than one element.
- 11. bond/ a chemical bond that involves sharing a pair of electrons between atoms in a molecule.
- 13. promotion/ A statement describing the populations of electronic energy sublevels of an atom
- 14. bond/ a bond formed from the overlap of two parallel p-orbitals.
- 16. covalent bonds/ A covalent bond in which the electrons are not shared equally, giving the bond some ionic character
