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 |
