Any element with an atomic number greater than 10 is capable of hypervalency. Electrons in the valence shell of these elements can be placed into hybridized d-orbitals during bonding if it is necessary to reduce the formal charge on the central atom of a molecule. Examples include PF5, SF6, AsF5, and XeF4.
Among the elements listed, lead (Pb) can form compounds with an expanded octet, as it is a heavier element that can utilize d-orbitals for bonding. Krypton (Kr) is a noble gas and typically does not form compounds due to its complete octet. Silicon (Si) and boron (B) usually follow the octet rule, although boron can sometimes form compounds with less than an octet. Therefore, only lead can form compounds with an expanded octet from the elements provided.
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.
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.
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.
Copper, Silver, and Gold occur as elements instead of compounds.

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.
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.
Xenon can achieve a stable octet by forming compounds with other elements through electron-sharing, such as in xenon tetrafluoride (XeF4) or xenon octafluoride (XeF8). These compounds allow xenon to complete its valence shell and satisfy the octet rule.
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.
No, BCl3 does not follow the octet rule as boron only has 6 valence electrons in this molecule. Boron can form stable compounds with less than an octet due to its electron deficiency.
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.
Copper, Silver, and Gold occur as elements instead of compounds.
Yes, both Cu+ and Cu2+ violate the octet rule. Copper (Cu) is an exception to the octet rule due to its electron configuration, which allows it to have a partially filled d orbital. This leads to Cu forming compounds where it does not achieve a full octet of electrons.
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.
Boron typically forms compounds with only 6 electrons in its outer shell. Phosphorus can exceed the octet rule and accommodate more than 8 electrons due to the availability of d orbitals. Sulfur can have more than 8 electrons around it in certain compounds, such as sulfite and sulfate ions.
Boron does not need an octet in its valence shell because it is an exception to the octet rule due to its electron configuration and bonding behavior. Boron typically forms stable compounds with fewer than eight electrons in its outer shell.
