Chlorine and oxygen can bond in many ways: . There is very little, if any, involvement of the d-orbitals in bond formation. It can but it is highly undesirable since doing so will lead to a positive formal charge, which is extremely unfavorable for a very electronegative atom such as chlorine. Diatomic molecules. The sodium cation (Na +) and the chlorine anion (Cl-) are attracted to one another to form sodium chloride, or table salt. Can someone please explain? There are four different types of chemical bonds: polar covalent, nonpolar covalent, ionic, and hydrogen bonds. - helps chemist understanding how elements form chemical bonds. Molecules that are made up of 2 atoms of the same element bonded together and thats it! Iodine typically forms only 1 covalent bond, but sometimes elements like fluorine, chlorine, and oxygen can cause iodine to form 3, 5, or 7 bonds. ... How many covalent bonds does iodine form? Teacher says chlorine can only make one bond, but in chlorate ( ClO3-) Chlorine makes 3 single bonds. Carbon can form a maximum of 4 bonds because it requires 4 more electrons to get the octet configuration. Chlorine needs 1 bond go gain octet but since it has d orbitalls it can expand its covalency unlike elements of 1st period. Hypervalency can be explained with 3-center, 4-electron bonding. No of bonds a compund can form depends on its position in the periodic table. - can be written using the period table or an electron configuration chart. Chlorine can form five bonds with fluorine, as in chlorine pentafluoride, ClF5, and six bonds in the ClF6^- ion. But that wouldnt make sense since carbon can form 4 bonds, and by that explanation it would mean carbon could make quadruple bonds - which dont exist. [duplicate] Ask Question Asked 3 years, 7 months ago. 1 bond means 1 electron. Due to its positioning on the periodic table, chlorine has D orbitals that it can hybridize bonds into, and +5 is a viable oxidation state for chlorine in this molecule. Chlorine generally forms 1 bond only but it many compounds it does form multiple bonds. What is the IUPAC  chlorine monoxide, ClO, chlorine (II) oxide; chlorine peroxide, Cl 2 O 2, dimer of chlorine (II) oxide; chlorine dioxide, ClO 2, chlorine (IV) oxide; chloroperoxyl, ClOO; chlorine trioxide, ClO 3, chlorine (VI) oxide; dichlorine monoxide, Cl 2 O, chlorine (I) oxide; Three dichlorine dioxides: ClO dimer, Cl 2 O 2, chlorine (I) peroxide Festival of Sacrifice: The Past and Present of the Islamic Holiday of Eid al-Adha. A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. How many covalent bonds does chlorine form? Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. Active 3 years, 7 months ago. 3. No of bonds a compund can form depends on its position in the periodic table. Start reading more about 3c/4e bonding here: http://en.wikipedia.org/wiki/Three-center_four-ele... As you've probably learned, most elements have multiple oxidation states. How is this possible if it can only make one bond? As a result, although it shares its single electron with another atom in a covalent bond, the other electrons are not available for additional bonds. Each of the chlorine atoms gets an electron to fill its shell, and the aluminum loses three, giving it a filled shell too (remember, Aluminum has three extra electrons). However, being electronegative and having high positive charge, chlorine partially pulls back the electron pair of …
