Ionic and Covalent
Holt Physical Science Section 2
| Question | Answer |
|---|---|
| a bond formed by the attract between obsolete charged ions | Ionic Bond |
| a bond formed by the attraction between positively charged metal ions and the electrons around them | Metallic Bond |
| a bond formed when atoms share one or more pairs of electrons | Covalent Bond |
| a ion more made up of two or more atoms | Polyatomic Bonds |
| A bond forms when | Two atoms are joined together |
| Atoms bond when their ________ _________ interact | Valence Electrons |
| True or False: Bond atoms have an unstable electron configuration | Fales : Bonded atoms have a "stable" electron configuration |
| True of False : Bonds can bend without breaking | True |
| A _____ behaves more flexible like strings | Bond |
| Stable electron configurations is the result of a | A positive Ion and A negative Ion |
| One positive ion and one negative ion make up a __________ | formula unit |
| __________ ___________ are in the form of networks not molecules | Ionic compounds |
| How do ionic compounds conduct electricity | when melted or dissolved |
| True of False : Electrons are free to move from atom to atom | True |
| Are metals flexible or unflexible? | Flexible |
| Covalent bonds are often formed between ______ atoms | non-metal |
| Convalent compounds are be made up of what 3 things? | Solids, Liquids, or Gases |
| True of False: Most covalent bonds have high melting points | False: No most have low melting points |
| When electrons are equally attracted to the positive nucleus of a atom this is called | Nonpolar covalent bonds |
| Atom joined by covalent bond share | Electrons |
| Can atoms share more than one pair of electrons? | Yes |
| Are electrons always shared equally in an atom ? | No. Electrons are not always equal in an atom |
| An unequal sharing of electrons forms a | polar covalent bond |
