Title: What is the maximum number of covalent bonds an element with atomic number 8 can make with hydrogen? Post by: rj957 on Dec 2, 2012 The element with atomic number 8 would need 2 electrons to fill its valence shell, where as hydrogen only needs 1 to fill its valence shell right?
The answer to this is 2 maximum covalent bonds, but I cannot figure out why. Science savvy people heeeelp I have a bio 2 exam coming up and my professor and TA are slow at responding to email! Thanks! Title: What is the maximum number of covalent bonds an element with atomic number 8 can make with hydrogen? Post by: Mickymouse on Dec 2, 2012 This element is oxygen. It needs 8 electrons to fill its valence shell. Two electrons are in a lower shell. That leaves six in its valence shell. Hydrogen contributes one electron. So two hydrogens will complete the valence shell of oxygen.

Title: What is the maximum number of covalent bonds an element with atomic number 8 can make with hydrogen? Post by: micphy on Dec 2, 2012 Element having atomic no. 8 need 2 electron to acheive a stable elctronic configuration i.e. 2,8. The H atom have only 1 electron and need only 1 electron to attain a stable configuration. Therefore, 2 covent bonds will be formed.
