| Question | Answer |
|---|---|
| Symbols and subscripts indicating the number of atoms of an element in a compound | chemical formula |
| The force that holds atoms together in a compound | chemical bond |
| A charged particle that has more or fewer electrons than protons | ion |
| The force of attraction between oppositely charged ions | ionic bond |
| The force of attraction between atoms sharing electrons | covalent bond |
| Neutral particle formed as a result of sharing electrons | molecule |
| A molecule with one end slightly negative and one slightly positive, but an overall neutral charge | polar molecule |
| A molecule in which electrons are equally shared | nonpolar molecule |
| A bond in which all outer shell electrons are shared by all electrons in the compound | metallic bond |
| What type of bond is formed by shared electrons? | covalent (covalent compounds cooperate) |
| What type of bond is formed by the transfer of electrons? | ionic (Ions Transfer --> I.T.) |
| What type of bond makes individual molecules? | covalent |
| What type of bond makes crystals of repeating 3D patterns? | ionic |
| What type of bond forms between a metal and a nonmetal? | ionic |
| What type of bond forms between only nonmetals? | covalent |
| What type of bond can form double or triple bonds? | covalent |
| What type of bond hold table salt (NaCl) together? | ionic |
| How many atoms of each element? Hg(NO3)2 | Hg : 1 N: 2 O:6 (Remember to multiply the elements in the parentheses by the subscript 2) |
