Draw relative energy levels diagrams for homonuclear diatomic molecules of period 2 elements. 2C+(O)2=2CO. The electronic configuration for F 2 is: s 2s2 s* 2s2 s 2p2 p 2p4 p* 2p4. What scientific concept do you need to know in order to solve this problem? The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. All choices have the electrons filled to: (sigma 2s)^2(sigma*2s)^2(sigma2p)^2(pi2p)^4. Our tutors have indicated that to solve this problem you will need to apply the Bond Order concept. he volume of a sample of gas (2.49 g) was 752 mL at 1.98 atm and 62 C. What is a molecule ?3.

C=49 g O=?, which of the following does not precipitate chemically in electrolytic process, find the mole fraction of carbon. Still have questions? 12valence electrons.c. Thus, the relative energy level diagram of \(\ce{O2}\) and \(\ce{F2}\) has the following arrangement: This electronic configuration indicates a bond order of 2, and the bond can be represented by \(\ce{O=O}\). , etween atomic number and mass number.6.Draw the Bohr's model of atom.7. f2 Q. The next six electrons will go in the 2p orbital. Fluorine is the ninth element with a total of 9 electrons. The electronic configurations agree with the experimental bond lengths and bond energies of homonuclear diatomic molecules of second-period elements. The argument regarding bond lengths, bond orders, and bond energies given for \(\ce{O2}\) and \(\ce{F2}\) above applies to all these molecules. You can follow their steps in the video explanation above.

The formation of bonds from the linear combination of atomic orbitals is the same as that of the valence bond theory. What is the bond order of B2-?Is B2-paramagnetic or diamagnetic?a. Fluorine is the ninth element with a total of 9 electrons. The electronic configuration for \(\ce{F2}\) is: This electronic configuration shows a single \(\ce{F-F}\) bond in the molecule for the reasons given for the \(\ce{O2}\) molecule. The total # of electrons is 7*2 - 1 = 13. For the second period elements, the 2s and 2p orbitals are important for MO considerations. 13 valence electrons.d. aayush5789 is waiting for your help.
