| Question | Answer |
|---|---|
| chemical bond | the sharing or transfer of electrons that results in atoms being "joined" together |
| covalent bond | a chemical bond in which electrons are shared |
| ionic bond | a chemical bond in which electrons are transferred, forming ions which then attract one another |
| non-polar covalent bond | a chemical bond in which the electrons are shared evenly between the two atoms |
| polar covalent bond | a chemical bond in which the electrons are shared unevenly between the two atoms |
| molecule | a group of atoms that are held together by (covalednt)chemical bonds |
| molecular formula or chemical formula | a way of showing the number and type of molecules that are bonded together using element symbols and subscripts, such as NaCl or CaCl2 |
| octet rule | atoms will gain, lose, or share electrons in order to fill their outer shell with 8 electrons (except hydrogen) |
| electron dot (Lewis) structure | a sketch that shows how the atoms in a molecule are connected and also shows the location of all of the valence electrons |
| bonding pair of electrons | a pair of electrons shared between two atoms, represented by a dash |
| lone pair of electrons | a pair of electrons that are not shared between two atoms, represented by two dots |
| single bond | a chemical bond consisting of one pair of electrons shared between two atoms |
| double bond | a chemical bond consisting of two pairs of electrons shared between two atoms |
| triple bond | a chemical bond consisting of three pairs of electrons shared between two atoms |
| polyatomic ions | a group of atoms held together by covalent bonds, but act as a unit as a charged ion which can form ionic bonds with other ions |
| metallic bond | a chemical bond between two metals where the electrons move freely between all of the atoms |
