Possible Answers: Crystal structure Cations and anions Sharing electrons between atoms Correct answer: Sharing electrons between atoms Explanation: To achieve an octet of valence electrons, atoms can share electrons so that all atoms participating in the bond will have full valence shells. Covalent bonds, by definition, result from the sharing of one or more pairs of valence electrons. How many single covalent bonds would the element sulfur be expected to form in order to obey the octet rule? Correct answer:  Explanation: The key to this problem is that electrons in covalent bonds are shared and therefore "belong" to both of the bonded atoms. Sulfur is a nonmetal in group 6A , and therefore has 6 valence electrons. In order to obey the octet rule, it needs to gain 2 electrons . It can do this by forming 2 single covalent bonds. How many single covalent bonds would the element selenium be expected to form in order to obey the octet rule? Correct answer: Explanation: The key to this problem is that electrons in covalent bonds are shared and therefore "belong" to both of the bonded atoms. Selenium is a nonmetal in group 6A , and therefore has 6 valence electrons. In order to obey the octet rule, it needs to gain 2 electrons. It can do this by forming 2 single covalent bonds. Which of the following constitutes a covalent bond?
Possible Answers: Spin pairing of electrons All of these Atoms of similar electronegativities Constructive interference between atomic orbitals Electron pair shared between two neighboring atoms Correct answer: All of these Explanation: A chemical bond is considered covalent if there is sharing of one or more pairs of electrons between atoms. As opposed to a covalent bond, an ionic bond can involve the transfer of electrons from one atom to another resulting in a high charge differential between two atoms in order for them to acquire a full octet. As described by the Pauli Exclusion Principle, every pair of electrons must consist of spin-up paired with spin-down. It states that no more than two electrons may occupy an orbital, and in full electron orbitals, the spin of one must cancel the spin of the other so their spins will have a zero net spin/angular momentum. Chemical bonds are made up of orbitals, which are simply waves that have wave functions. Wave functions tell us the likelihood that an electron can be found within an orbital. Constructive interference of two wave functions/orbitals occur when the two waves are in phase and result in a new wave function, or in other words a chemical bond.

When it does this this is described as expanding the octet and it involves the sulfur making use of each and every one of its valence electrons. An example of sulfur with 6 covalent bonds is the sulfur atom in sulfuric acid, H2SO4 H 2 S O 4 .
How many covalent bonds can sulfur form?Sulfur has one more electron pair in its 3s subshell so it can undergo excitation one more time and place the electron in another empty 3d orbital. Now sulfur has 6 unpaired electrons which means it can form 6 covalent bonds to give a total of 12 electrons around its valence shell.
How many covalent bonds can group 16 elements form?Oxygen and other atoms in group 6A (16) obtain an octet by forming two covalent bonds. Fluorine and the other halogens in group 7A (17) have seven valence electrons and can obtain an octet by forming one covalent bond.
Can sulfur Form 4 bonds?In addition, sulfur can also form four-coordinate 'hypervalent' bonds, where its formal number of valence electrons exceeds eight. Compounds containing these bonds are known as sulfuranes.
