properties
| Term | Definition |
|---|---|
| ATOMIC NUMBER | the number of protons around the nucleus A proton is a positively charged elementary particle |
| ATOMIC WEIGHT | the average weight of an atom of an element |
| ELECTRON AFFINITY | the quantitative measure, usually given in electron-volts, of the tendency of an atom or molecule to capture an electron and to form a negative ion. |
| ELECTRONEGATIVITY | containing negative electricity; tending to migrate to the positive pole in electrolysis. |
| electrolysis | the passage of an electric current through an electrolyte with subsequent migration of positively and negatively charged ions to the negative and positive electrodes. |
| ATOMIC RADIUS | the radius of an atom |
| METALLIC CHARACTER | Metallic character is the name given to the set of chemical properties associated with elements that are metals. These chemicals properties result from how readily metals lose their electrons. |
| types of chemical bonds formed | Ionic Bonds- the electrostatic bond between two ions, covalent chemical bond-the bond formed by the sharing of a pair of electrons by two atoms , Metallic bonds- the type of chemical bond between atoms in a metallic element |
| valence electrons | an electron of an atom, located in the outermost shell of the atom, that can be transferred to or shared with another atom. |
| IONIZATION ENERGY | the amount of energy required to remove an electron from an atom to form a cation |
| MELTING POINT | the temperature at which a solid substance melts or fuses. |
| NUMBER OF BONDS FORMED. | 3 bonds total |
