If ICl -2 does not obey the octet rule then how many electrons are around the central atom?
ICl2- is 10, if you are in Ap Chem on WebAssign then this is probably what you are looking for....
-I already got it right on WebAssign:)
The octet rule states that chemical compounds tend to form so that each atom has an octet of electrons in?
Will an atom containing two electrons in its outer orbit loose or gain electrons to form an ionic bond?
No, atoms do not bond to form electrons because electrons cannot be "formed" in this manner. Instead, bonds are formed when atoms share the electrons they possesses. Each atom wants to gain a full octet of electrons in its outermost shell. Until the atom has eight, it cannot be happy and remains "unstable." So, through the process of bonding, an atom will share its valence electrons (electrons in the outer shell) with another atom. This…
What is the number of bonding electron pairs and lone pairs of electrons surrounding the central atom in CCl4?
Carbon is the central atom in this molecule, and carbon is within the second period of the periodic table, thus carbon obeys the octet rule. The molecular shape will be tetrahedral, and with respect to VSEPR, there are no lone pairs. From the periodic table, we see that carbon has four valence electrons.
Simply put, Selenium (Se) is the central atom with four Flourines (F) around the atom. There is four single bonds that connects the Flourines to the Selenium atom. However, since the SeF4 is one of those compounds that is unsatisfied by the Octet rule, a lone pair of electrons should be placed on the Selenium atom.
The Lewis dot structure of SO2, or sulfur dioxide, has a central atom of sulfur that violates the octet rule. The central atom of sulfur has one lone pair and is double bonded to two oxygen atoms. Sulfur has valence electrons in the 3rd energy level, allowing access to the 3d sublevel and more than 8 valence electrons.
An octet electron arrangement is where an atom has 8 valence electrons. It's very stable and unreactive. Some metal atoms tend to donate its electrons and the electrons accepted by non-metal atom. This is called ionic bonding. Some non-metal electron share electron among themselves to achieve octet electron arrangement. This is called covalent bonding. Conclusion is, all elements achieve octet electron arrangement.
What is likely to happen to an atom of oxygen that does not contain maximum number of electron in outermost energy level?
The octet rule says that the most desirable state for an atom is to have its outer shell filled with 8 electrons. This is the governing factor behind the formation of most ionic compounds. It will bind with other atoms, taking electrons, and if an octet is possible without disturbing another octet, the electrons will move, turning the atom of oxygen into the oxide anion (O2-).
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
