Chapter 5: Covalent Bonds and Introduction to Organic Molecules - Chemistry Each atom starts out with an odd number of electrons in its valence shell: The two atoms can share their unpaired electrons to make a covalent bond: We note that the H atom has a full valence shell with two electrons, while the F atom has a complete octet of electrons. Some molecules are not able to satisfy the octet rule by making only single covalent bonds between the atoms. 2.6 Ionic and Molecular Compounds - Chemistry 2e | OpenStax document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Address: 9241 13th Ave SW When atoms share electrons, they can fill their outermost electron shells, which is a stable inert gas configuration.

To increase the overall energy of the molecule and decrease A molecule of octane, which is a component of gasoline, contains 8 atoms of carbon and 18 atoms of hydrogen. The carbon atoms are bonded together, with each carbon also being bonded to two hydrogen atoms. F atoms have seven electrons in their valence shell: These two atoms can do the same thing that the H atoms did; they share their unpaired electrons to make a covalent bond. Helmenstine, Anne Marie, Ph.D. "Covalent or Molecular Compound Properties." Why are the valence electrons of an atom the only electrons likely to be involved in bonding to other atoms? Work Plz. Negative ions: when any atom accepts electron it forms negative ion. Molecular compounds cannot conduct electricity because they lack freely moving electrons. Examples include such familiar substances as water (H 2O) and carbon dioxide (CO 2). This means that neither atom can easily take or give away electrons to the other atom, so they have to share electrons in order to fill their outermost electron shells and become more stable.
