🗑
|
||||
| electron dot diagrams | includes the symbol for the element surrounded by dots. Each dot stands for one valence electron
🗑
|
||||
| chemical bond | is the force of attraction that holds two atoms together as a result of the rearrangement of electrons between them
🗑
|
||||
| ion | is an atom or group of atoms that has an electric charge
🗑
|
||||
| polyatomic ion | ions that are made of more than one atom and react as a unit
🗑
|
||||
| ionic bond | is an attraction between two oppositely charged ions
🗑
|
||||
| ionic compound | a compound that consists of postive and negative ions
🗑
|
||||
| chemical formula | is a combination of symbols that shows the ratio of elements in a compound
🗑

||||
| molecule | a neutral particle made of two or more atoms joined by covalent bonds
🗑
|
||||
| double bond | the two atoms share two pairs of electrons
🗑
|
||||
| triple bond | in which their atoms share three pairs of electrons
🗑
|
||||
| molecular compound | is a compound that is composed of molecules that are covalently bonded
🗑
|
||||
| polar bond | a covalent bond in which electrons are shared unequally
🗑
|
||||
| non polar bond | if two atoms pull equally on the electrons neither atom become charged
🗑
|
||||
| alloy | is a mixture made of two or more elements, at least one of which is a metal. Stronger and less reactive than pure metals
🗑
|
||||
| metallic bond | an attraction between a positive metal ion and the many electrons surrounding it...the positive charged metal ion are embedded in a sea of valence electrons
🗑
