Which Elements Can Form Expanded Octets
Which Elements Can Form Expanded Octets. C f as li all of the above elements can form compounds with an expanded octet. Web the octet rule applies well to atoms in the second row of the periodic table, where a full valence shell includes eight electrons with an electron configuration of s 2 p.
Some examples are;phosphorous pentachloride pcl5sulfur. Elements that cannot have an expanded octet are:. Web these elements include hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon.
Some Examples Are;Phosphorous Pentachloride Pcl5Sulfur.
In methane (ch4), carbon has a full octet (eight valence electrons). Elements that can have expanded octet. Web expanded octet occurs when an atom is able to have more than 8 valence electrons.
A Valence Shell Electron Count That Exceeds Eight Electrons.
Some examples are;phosphorous pentachloride pcl5sulfur. Postby 705383815 » fri nov 13, 2020 4:18 am. N=3 or higher) can form compounds with an expanded octet.
O Submit Request Answer Part B Which Elements Should Never Have Expanded Octets?.
Web this means only period 2 elements such as c, n, o and f cannot expand octet and have to obey octet rule. Web sulfur, phosphorus, silicon, and chlorine are common examples of elements that form an expanded octet. C f as li all of the above elements can form compounds with an expanded octet.
Sulfur, Phosphorus, Silicon, And Chlorine Are.
Which elements can have an expanded octet? Web elements before period 3 cannot form expanded octets, as n=1 and n=2, meaning only the s and p orbitals exist, which hold a maximum of 8 electrons combined. Web the octet rule applies well to atoms in the second row of the periodic table, where a full valence shell includes eight electrons with an electron configuration of s 2 p.
N=3 Or Higher) Can Form Compounds With An Expanded Octet.
Which elements can have expanded octets? Phosphorus pentachloride (pcl5) and sulfur. For example, in so₃, the sulfur atom forms 6 covalent bonds, hence it has 12 valence electrons.
