there is no chemical reaction which ionises helim. the ionization energy is 2372 kJ/mol which is the highest of all the elements. The He+ ion can be formed in for example plasmas. He2+ can also be formed - this is the bare nucleus containing two protons.
Helium is an inert gas.
yes it schould be
helium doesn't form compounds
Helium has no net electric charge. And its electronegativity is zero.
Hydrogen and helium are formed in Sun.
Helium is an inert gas.
because potassium is the total opposite of ionic bond
Cesium is the element that is most likely to form an ionic compound with chlorine because it readily loses an electron to form Cs+ ions, which can then combine with Cl- ions to form CsCl, known as cesium chloride. Helium and iodine do not typically form ionic compounds with chlorine.
Helium does not typically form bonds with other elements. It exists as a noble gas with a stable electron configuration, so it does not form ionic or covalent bonds.
helium has completely filled orbitals and does not react with any element.
Potassium and helium do not form an ionic bond because they belong to different groups on the periodic table. Potassium is a metal in group 1, while helium is a noble gas in group 18. Due to their large difference in electronegativity and stability, they are unlikely to transfer electrons to form an ionic bond.
Metals form ionic compounds with non metals. Fe is a metal. So it is likely to make ionic bonds with Cl.
He, helium, is an element. It is a noble gas and it does not form any chemical compounds.
No, it rarely bonds with other elements, and if it does the only one it would bond with would be Fluorine, which they have done before, and if and when it bonds with fluorine and/or oxygen, it would form a covalent bond. If you were to to take either of the two elements and try to perform an chemical reaction, when you find the electro negativity (ΔEn, which is equal to En2-En1) you will notice that it will fall below 0.5 or greater than 1.7 , which will be a covalent bond (an ionic bond will be between 0.5 and 1.7).
Helium is a mono-atomic element and has completely filled s-orbitals. So it is stable and non-reactive (chemically inert). Hence helium will not form any type of bonds with other elements.
Helium has a stable (full) valence shell (1s2) which means that it will have a high ionization energy (the energy required to remove an electron). In fact, helium has the highest ionization energy of any element. However, this does not mean that helium cannot form ions. It just means that it will require a lot of energy to do so and this does not happen under normal conditions.
helium is after haydrogen it means hygrogen is lighter than helium. now the question arises that "Q.1"why we use helium instead of hydrogen coz hydrogen is lighter than helium. Ans.1:hydrogen has 1 electron in its 1st shell and helium has it's complete shell with two electron. When we fill hydrogen in the baloon they form ionic bond... so it is used double...
