19 terms
Terms | Definitions |
|---|---|
 Chemical bonding | Any of several forces, especially the ionic bond, covalent bond, and metallic bond, by which atoms or ions are bound in a molecule or crystal |
| valence electrons | An electron in an outer shell of an atom that can participate in forming chemical bonds with other atoms |
| chemical stability | making the outer most energy level happy |
| compound | things needed to make neutrality |
| Chemical formula | a combination of symbols used to express the chemical composition of a substance |
| electron dot diagrams | a diagram representing valence electrons |
| covalent bonds | force of attraction between the nuclei of atoms and the electrons shared by the atoms |
| lewis dot diagram | diagrams that show covalent bonding (sharing of electrons) |
| octet rule | all atoms are happy when surrounded by 8 electrons |
| metallic bond | formed through metals, bonding formed through positively charged ions and electrons through metal |
| ion | charged atoms |
| anion | negatively charged atom, gains negative charges electron(s) |
| molecule | The smallest particle into which an element or a compound can be divided without changing its chemical and physical properties; a group of atoms that is held together chemically |
| cation | positively charged ions, loses negative charge electrons |
| oxidation number | positive or negative number assigned to an element to show combining ability in a compound, indicates how many e- an atom gains loses or shares when bonding |
| ionic bond | force of attractions between 2 opposite charged ions |
| nonmenclature | system of naming compounds |
| binary compound | compound made up of 2 elements, 1 metal & 1 nonmental, ionic compounds, binary ionic bond |
| diatomic compound | a molecule that consists of 2 atoms made up of the same element. |
