SF6
Yes. Both O-F bonds are single covalent, so all three atoms can claim 8 electrons.
Two elements that can form compounds that are exceptions to the octet rule are boron and phosphorus. Boron compounds often have fewer than 8 valence electrons, and phosphorus compounds sometimes have more than 8 valence electrons due to expanded octets.
Sulfur (S) would be the central atom, and it will have 6 Cl bonded to it by single bonds. Each Cl will have 3 lone pairs of electrons around them. S will have 12 electrons but it can have an expanded octet, and doesn't have to have 8 electrons.
"To use Lewis theory to determine the formula of an ionic compound, determine the number of valence electrons lost by the metal to form an octet, and the number of electrons gained by the nonmetal to form an octet." Refer the link below for further reading.
Their valance electrons form an octet. Each compound wants to have 8 valence electrons (which forms an octet). Groups 1 and 2 have 1 and 2 valence electrons respectively. 16 and 17 have 6 and 7 respectively. So together, they form 8.
Yes. Both O-F bonds are single covalent, so all three atoms can claim 8 electrons.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
No, metals tend to lose electrons to achieve a full octet.
Phosphorus need 3 electrons to complete its octet.
Elements which have d-orbitals (i. e. n=3 or higher) can form compounds with an expanded octet. Some examples are;Phosphorous Pentachloride PCl5Sulfur Hexafluoride SF6Dichloro Heptoxide Cl2O7
8: that's the meaning of "octet".
The element whose atomic, and therefore proton number, of 6 is Carbon (C) and of 17 is Chlorine (Cl). Carbon has a valence of 4 electrons meaning it needs to 'take in' four more electrons to fill its octet (and thus follow the octet rule). The chlorine has a valence of 7 electrons and therefore it only needs 1 electron to fill its octet. Through a covalent bond, where the electrons are 'shared' between the molecules, 4 Cl and 1 C can bond to form the compound CCl4. All of the elements have a full octet and form a tetrahedrally shaped molecule.
BF3 is considered an acid because it can readily donate a proton (H+) to a base, forming a bond with the base molecule. This proton donation behavior classifies it as a Lewis acid, which reacts by accepting an electron pair from a Lewis base.
The octet rule.
Well according to the octet rule the a compound must have 8 valance electrons to be stable.
i think 4 is the valency of tetrachloride
The Octet Rule states that atoms are most stable when they have 8 electrons in their outer shell, except for hydrogen and helium, which are stable with 2 electrons in their outer shell.
