| Questão | Responda |
| Electron | a subatomic particle with a single negative charge; one or more electrons move around the nucleus |
| Isotopes | one of several atomic forms of an element each containing different number of neutrons and different in atomic mass |
| Valence Electrons | the electrons in the outermost electron shell |
| Chemical Bonds | an attraction between two atoms resulting from a sharing of outer shell electrons or the presence of opposite charges on the atom; the bonded atoms gain compounds outer electron shells |
| Covalent Bonds | A type of strong chemical bond in which two atoms share one pair of valence electrons |
| Polar Covalent Bonds | a type of covalent bond between atoms that differ in electronegativity. the shared electrons are pulled closer to the more electronegative atom. making one slightly negative and the other slightly positive |
| Electronegativity | the attraction of an atom for the electrons of a covalent bond |
| Anion | A negatively charged ion |
| cation | an ion with a positive charge produced by the loss of one or more electrons |
| Hydrogen Bond | a type of weak chemical bond formed when the slightly positive hydrogen atom of a polar covalent bond in one molecules is attracted to the slightly negative atom of a polar covalent in another bond |
