Definition
| A short way to show the ratio of atoms in chemical reactions using symbols. Reactants produces Products |
|
|
Term
|
Definition
A chemical bond between two oppositely charged ions (metals which lose e- and non-metals which gain e-)
|
|
|
Term
|
Definition
| Electrons that are in the shell farthest from the nucleus, which are held the weakest and are involved in chemical reactions |
|
|
Term
|
Definition
| Elements in the same group have the same number of valance electrons. The number of valance electrons across a period increases by one |
|
|
Term
|
Definition
| An atom that loses electrons is left with more protons (+) than electrons (-) so the ion has a positive charge |
|
|
Term
|
Definition
| An atom that gains electrons has more electrons (-) than protons (-) so the ion has a negative charge |
|
|
Term
|
Definition
| An atom (or group of atoms) that obtain an electric charge by losing or gaining valance electrons |
|
|
Term
|
Definition
An ion made up of one atom.
ex: Chlorine Ion (Cl-),
Sodium Ion (NA+). |
|
|
Term
|
Definition
An ion made up of more than one atom, but it can be treated as one ion
ex. Hydroxide (OH-),
Ammonium (NH4+). |
|
|
Term
|
Definition
| Atoms want to have their outer most energy shell completely filled by gaining or losing electrons. This will result in the atoms having an electric charge |

Term
|
Definition
| Can conducts electricity if it is melted to a liquid or dissolved in water because then the ions are able to flow easily |
