1.7 ActivitiesRemember1. Non-metals combine together to create covalent bonds2. A covalent bond is when two or more atoms share electrons to create a full outer shell3. The electron dot diagram represents how many electrons are in the outer shell of an atom4. They exist as gas, liquids, and solids, have a low melting temperature, generally dont conduct electricity, insolubleThink1. A single covalent bond only has the elements involved share one electron, whereas a triple covalent has the elements share three electrons2. A) single and doubleB) singleC) single and triple3. .4. Noble gases do not form covalent compounds because they have no spare electrons to share, since they have a full outer shell5. CO2 and O2 are both molecules because they are both formed with covalent bonds
