∙ 12y ago

Updated: 6/14/2024

Elements which have d-orbitals (i. e. n=3 or higher) can form compounds with an expanded octet. Some examples are;

Phosphorous Pentachloride PCl5
Sulfur Hexafluoride SF6
Dichloro Heptoxide Cl2O7

Elements in period 3 and beyond, such as sulfur, phosphorus, chlorine, and bromine, can form compounds with an expanded octet. These elements have empty d orbitals available for bonding, allowing them to exceed the octet rule and form compounds with more than eight electrons around the central atom.

An octet of electrons means the last shell of the atom has 8 electrons. The last column in the Periodic Table (also called noble gases) has all the elements that contain an octet of electrons such as Helium, Neon, and Argon, to name a few.

I think it is the Noble gases or the inert gases (they have full shells). Check it up on Google and you will get a full explanation :)

The noble gases have a complete octet. If you go across the groups (1a to 8a), left to right. They have 1 to 8 of the octet in order. This gives them remarkable stability.

How does neon obey the octet rule when reacting to form ionic compounds?

Neon does not typically form ionic compounds because it already has a full valence shell with 8 electrons, satisfying the octet rule. Its electron configuration (1s^2 2s^2 2p^6) makes it very stable and unreactive with other elements.

What is a element that will not form a compound?

Helium is an element that typically does not form compounds due to its stable electronic configuration with a full outer shell of electrons.

How does sodium obey the octet rule when reacting to form compounds?

Sodium typically loses its one valence electron to achieve a stable electron configuration, resembling the nearest noble gas (Neon), thereby obeying the octet rule. This electron loss allows sodium to form a stable ionic bond with other elements by attaining a complete outer shell with 8 electrons.

Ions of the elements oxygen (O) sulfur (S) and selenium (Se) usually have charges of -2. Ions of the elements fluorine (F) chlorine (Cl) and bromine (Br) usually have charges of -1.?

That's correct. Oxygen, sulfur, and selenium typically form ions with a charge of -2 by gaining two electrons to achieve a stable octet. Fluorine, chlorine, and bromine usually form ions with a charge of -1 by gaining one electron to achieve a stable octet.

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.

Related Questions

How many what elements can for compounds with expanded octet....I O Cl Xe...?

Elements in the third period or beyond (Si and beyond) in the periodic table can form compounds with expanded octets. This includes elements such as sulfur, phosphorus, chlorine, and xenon. These elements can often exceed the octet rule by forming more than 8 electrons in their valence shell in some compounds.

Why can phosphorus have an expanded octet?

Phosphorus can have an expanded octet because it has empty d orbitals in its valence shell, allowing it to accommodate more than eight electrons and form more than four bonds.

Why do most of the elements on a periodic table like to form bonds with other elements?

To complete their octet

Does xenon atom fit the Octet rule?

No, xenon does not always follow the octet rule. It is a noble gas and can form stable compounds that have more than eight electrons around the xenon atom, known as expanded octet.

How can xenon achieve stable octet?

Xenon can achieve a stable octet by forming compounds with elements that can share their electrons with xenon. For example, xenon can form compounds with fluorine, chlorine, or oxygen where xenon acts as the central atom and bonds with these more electronegative elements to complete its octet.

Does uranium have an octet?

Uranium typically forms compounds where it does not have an octet due to its ability to expand its valence shell beyond eight electrons. Uranium can often exceed the octet rule in its bonding arrangements.

What are the limitations of octet rule?

The octet rule does not apply to all elements, especially those with more than 8 valence electrons. It also does not explain the bonding in molecules with odd numbers of electrons or in species with expanded octets, such as phosphorus pentachloride. Additionally, the rule is a simplification and does not account for molecular geometry and resonance structures.

Which elements can combine with boron to form octect?

Boron typically forms compounds by sharing electrons, rather than obtaining a full octet. It can form compounds with elements such as hydrogen and fluorine, but it often displays unique bonding patterns due to its electron deficiency.

How does the octet rule relate how active an element is?

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a stable configuration with 8 electrons in the outermost shell. Elements that already have a complete octet, such as noble gases, are stable and less likely to form chemical bonds, making them less reactive. Conversely, elements that do not have a complete octet in their outer shell are more likely to react with other elements to achieve stability, thus they are more reactive.

Why can sulfur utilize an expanded octet while oxygen cannot?

Sulfur can utilize an expanded octet because it has empty d orbitals in its third energy level, allowing it to accommodate more than 8 electrons. Oxygen, on the other hand, does not have d orbitals in its third energy level, limiting its ability to form more than 8 electrons in its valence shell.

Why are element in the periodic table bond?

Elements bond to form compounds and thereby try to gain better stability by getting octet configuration.
