How many bonds can helium have
WebHydrogen and helium are the only two elements that have the lowest shell and no other shells. ... For example, an oxygen atom can bond with another oxygen atom to fill their outer shells. This association is nonpolar because the electrons will be equally distributed between each oxygen atom. Two covalent bonds form between the two oxygen atoms ... WebHydrogen can form one covalent bond to have two valence electrons. Hydrogen and helium are notable exceptions to the general rule that atoms share an appropriate number of valence electrons to obtain eight. Therefore, with its single electron in the valence shell, the number of covalent bonds that hydrogen can form is one.

And it undergoes nuclear reactions when there is a high temperature such... WebSep 26, 2016 · So they will make as many bonds as they need to achieve this, knowing that each bond adds one more electron. Fluorine: there are 7 valence electrons. So, we need one more. So fluorine will typically make one bond. Helium: this is a special case, as with hydrogen. These only need 2 valence electrons.
