The electronegativity of helium is 5.5
What else can I help you with?
Why oxygen is more electronegative than helium?
Oxygen has more protons in its nucleus compared to helium, creating a stronger pull on electrons, leading to higher electronegativity. Additionally, oxygen has a smaller atomic size, allowing it to hold on to electrons more tightly, enhancing its electronegativity compared to helium.
Which inert gases can form compound?
Helium, neon, argon, krypton, xenon, and radon are inert gases that can form compounds, primarily with highly electronegative elements such as fluorine and oxygen.
What are chemical changes of helium?
Helium does not undergo chemical changes under normal conditions because it is a noble gas with a full outer electron shell, making it very stable. Helium can only react under extreme conditions, such as high pressure and temperature, to form compounds with highly electronegative elements.
When will an atom be electronegative?
An electronegative atom gain electrons.
Which is more electronegative Sr or Be?
Sulfur is more electronegative than beryllium.
What is an electronegative?
An electronegative atom is an atom that can attract a bonding pair of electrons from another atom. Fluorine is the most electronegative element.
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
What other elements make compounds with helium?
Helium does not readily form compounds with other elements due to its stable electron configuration. However, it can form weakly bound compounds with highly electronegative elements such as fluorine under extreme conditions.
What of these elements is the most electronegative?
Fluorine is the most electronegative element.
When very electronegative atoms with lower electronegative like lithium What is the result?
When very electronegative atoms interact with less electronegative atoms like lithium, the very electronegative atoms tend to attract the shared electrons more strongly. This can result in the formation of polar covalent bonds where the electron distribution is uneven. This leads to the electronegative atom being partially negative and the less electronegative atom being partially positive.
What compounds contain helium?
Helium is a noble gas and typically does not form compounds with other elements due to its stable electron configuration. However, in extremely rare cases, helium can form compounds with highly electronegative elements under specific conditions, such as with fluorine to form helium difluoride (HeF2) or with oxygen to form helium oxide (HeO2).
Which is most electronegative metal?
Fluorine is the most electronegative element and not a metal. Among metals, the most electronegative is cesium.
