Which of these does not follow the octet rule NF3 CO2 OF2 Br2 NO?
See the Related Questions to the left for how to solve this problem.First draw the Lewis Dot structures of each molecule, then count the valence electrons of each atom in the structures. Find the one that doesn't have eight!In this case, there is actually a little trick. To follow the octet rule, each atom must have 8 valence electrons in the structure, right? Therefore, the molecule must have an even number of total electrons for that to work. So which molecule does not have an even number of total electrons?
Which obeys the octet rule PF5 Cs2 BBr3 CO3 2?
PF5 obeys the octet rule as it has 5 bonding pairs of electrons around the central phosphorus atom, satisfying the octet. Cs2 does not follow the octet rule as Cs is in Group 1 and can only form ionic bonds. BBr3 is an exception to the octet rule as boron has only 6 electrons around it due to the empty d orbital. CO3 2- also obeys the octet rule as each oxygen atom has a complete octet.
Why do transition metals not have Lewis dot structures?
They do! Bonding with transition metals can definitely be drawn using Lewis dot structures. They are generally not taught until you reach high level chemistry courses however because they do not follow the 8-electron or octet rule as most other elements as taught in high school. Transition metals have valence bonding electrons in 3 different orbitals: s, p, and d(as opposed to say, carbon, oxygen, nitrogen, etc. that only have s and p valence orbitals). Because of the additional d-orbitals in transition metals, which can hold up to 10 electrons, transition metals follow what is known as the 18-electron rule (2 from the s-orbital plus 6 from the p-orbitals plus 10 from the d-orbitals. This 18-electron counting rule works the same as the octet rule, except now you need to use both your fingers and toes! ;-)
Does the formula for potassium iodide illustrate the octet rule?
Yes, it does.
Does MgCl2 follow the octet rule?
No, MgCl2 does not follow the octet rule. Magnesium typically forms ionic bonds with a 2+ charge, so in MgCl2, magnesium has only 8 electrons in its outer shell (2 from Mg and 6 from 2 Cl atoms), not a full octet.
What is the octet rule in terms of lewis structures?
Octet rule states that each electron wants to complete its octet ( 8 electrons in the outermost shell) or a duplet (in case of hydrogen and helium).
The two Lewis structure for ozone satisfy the octet rule and are resonance structures?
In the Lewis structures of ozone, each oxygen atom has a full octet of electrons, satisfying the octet rule. Additionally, ozone exhibits resonance because the double bond can be located on different oxygen atoms, resulting in two equivalent resonance structures.
The number of resonance structures for the nitrate ion that satisfies the octet rule is?
There are three resonance structures for the nitrate ion that satisfy the octet rule. In each of these structures, each oxygen atom has a full octet by sharing electrons through double bonds with the nitrogen atom.
Is NH3 a resonance structure?
No, NH3 is not a resonance structure. Resonance occurs when it is possible to draw multiple valid Lewis structures for a molecule, but for NH3, there is only one correct Lewis structure based on the arrangement of the atoms and the octet rule.
Is PF5 an exception to the Lewis octet rule?
Yes, PF5 is an exception to the Lewis octet rule. Phosphorus has 10 electrons around it in PF5, exceeding the octet rule. This is due to the availability of d-orbitals in the valence shell of phosphorus for accommodating extra electrons.
How do metals obey the Lewis octet rule?
The elements can be described by dot structure. Metals combine with other elements to make its octet complete.
What is the Lewis octet rule?
idk okay so 1st add 2 -3 /4
What is the octet rule and how is it useful in drawing Lewis Dot Structures?
Most elements have a stable electron arrangement when they have 8 electrons in their outer shell (hydrogen and helium are exceptions, they are stable with only 2 electrons in their outer shell), and an octet is 8 of something, hence the octet rule. Lewis dot diagrams are drawn to show how many electrons are associated with any given atom, and how the atoms are shared, in the case of covalent bonding. Generally, each atom winds up with 8 electrons. Not hydrogen.
Do transition elements have Lewis dot structures?
Yes, transition elements can form Lewis dot structures. However, transition elements typically have valence electrons in more than one energy level, making their Lewis structures more complex compared to elements with a single valence shell.
How can one draw Lewis dot structures for elements?
To draw Lewis dot structures for elements, determine the total number of valence electrons for the element. Then, place the electrons around the element symbol in pairs, following the octet rule (except for hydrogen and helium, which follow the duet rule). Remember to show all valence electrons and distribute them evenly around the element symbol.
What Lewis structure cannot be drawn without violating the octet rule?
A Lewis structure that violates the octet rule would be one where a central atom doesn't have an octet of electrons, but has less or more than eight electrons around it. Examples include molecules with an odd number of valence electrons, such as NO or radicals like NO2.
Why do neon and helium have different number of dot in their Lewis structures if they are in the same group?
Neon and helium have different number of valence electrons, which determine the number of dots in their Lewis structures. Helium has 2 valence electrons and will have 2 dots in its Lewis structure, while neon has 8 valence electrons and will have 8 dots in its Lewis structure, following the octet rule.
